**Choose the best term from the box.**

Question 1.

The number of square units needed to cover a flat surface is the ______________.

_________

Answer: Area

The number of square units needed to cover a flat surface is the area.

Question 2.

The distance around a shape is the ____________.

_________

Answer: Perimeter

The distance around a shape is the Perimeter.

**Find the area of the rectangle or combined rectangles.**

Question 3.

A = _____ square feet

Answer: 112 square feet

Explanation:

Given,

length = 14 ft

Width = 8 ft

Area of the rectangle = l Ã— w

A = 14 ft Ã— 8 ft

A = 112 square feet

Thus the area of the rectangle for the above figure is 112 square feet.

Question 4.

A = _____ square centimeters

Answer: 65 square cm.

Explanation:

Figure 1:

S = 3 cm

Area of the square = s Ã— s

A = 3 cm Ã— 3 cm

A = 9 square cm

Figure 2:

b = 11 cm

h = 4 cm

Area of the rectangle = b Ã— h

A = 11 cm Ã— 4 cm

A = 44 square cm

Figure 3:

b = 2 cm

h = 6 cm

Area of the rectangle = b Ã— h

A = 2 cm Ã— 6 cm

A = 12 square cm

Area of the composite figure is 9 sq. cm + 44 sq. cm + 12 sq. cm = 65 square cm.

**Find the unknown measure of the rectangle.**

Question 5.

A = _____ square yards

Answer: 136 square yard

Explanation:

Figure 1:

b = 12 yd

h = 8 yd

Area of the rectangle = b Ã— h

A = 12 yd Ã— 8 yd

A = 96 square yard.

Figure 2:

b = 16 yd

h = 1 yd

Area of the rectangle = b Ã— h

A = 16 yd Ã— 1 yd

A = 16 square yard.

Figure 3:

b = 4 yd

h = 6 yd

Area of the rectangle = b Ã— h

A = 4 yd Ã— 6 yd

A = 24 square yard.

The area of the composite figure is 96 square yard + 16 square yard + 24 square yard = 136 square yard.

Question 6.

Perimeter = 60 meters

width = _____ m

Answer: 12 m

Explanation:

Given,

Perimeter = 60 meters

length = 18 m

width = _____ m

The perimeter of the rectangle = l + w + l + w

P = 2l + 2w

60 m = 2 Ã— 18 m + 2w

60 m – 36 m = 2w

2w = 24

w = 24/2

w = 12 meters

Thus the width of the above rectangle is 12 meters.

Question 7.

Area = 91 square feet

height = _____ feet

Answer: 13 ft

Explanation:

Given,

Area = 91 square feet

base = 7 ft

height = _____ feet

Area of the rectangle = b Ã— h

91 sq ft = 7 ft Ã— h

h = 91/7

h = 13 ft

Thus the height of the above rectangle is 13 ft.

Question 8.

Area = 60 square inches

base = _____ in.

Answer: 10 inches

Explanation:

Given,

Area = 60 square inches

height = 6 in

base = _____ in.

Area of the rectangle = b Ã— h

60 square inches = b Ã— 6 in

b = 60/6

b = 10 inches

Thus the base of the above rectangle is 10 inches.

Question 9.

What is the perimeter of a rectangle with a length of 13 feet and a width of 9 feet?

P = _____ ft

Answer: 44 ft

Explanation:

Given,

l = 13 ft

w = 9 ft

The perimeter of the rectangle = l + w + l + w

P = 13 ft + 9 ft + 13 ft + 9 ft

P = 44 ft

Thus the perimeter of the rectangle is 44 ft.

Question 10.

Which pair of shapes has the same area?

Options:

a.

b.

c.

d.

Answer:

Explanation:

a.

4 Ã— 2 = 8

3 Ã— 3 = 9

8 â‰ 9

b.

4 Ã— 4 = 16

3 Ã— 5 = 15

16 â‰ 15

c.

3 Ã— 4 = 12

2 Ã— 6 = 12

12 = 12

Thus the correct answer is option c.

Question 11.

Jamieâ€™s mom wants to enlarge her rectangular garden by adding a new rectangular section. The garden is now 96 square yards. What will the total area of the garden be after she adds the new section?

Options:

a. 84 square yards

b. 96 square yards

c. 180 square yards

d. 192 square yards

Answer: 192 square yards

Explanation:

Given that,

Jamieâ€™s mom wants to enlarge her rectangular garden by adding a new rectangular section. The garden is now 96 square yards.

Add 96 square yards to the rectangular garden.

96 square yards + 96 square yards = 192 square yards

Thus the correct answer is option d.

Question 12.

A rectangular yoga studio has an area of 153 square feet. The width of the studio is 9 feet. What is the length of the studio?

lenght = _____ ft

Answer: 17 ft

Explanation:

Given,

A rectangular yoga studio has an area of 153 square feet.

The width of the studio is 9 feet.

Area of the rectangle = l Ã— w

153 square feet = l Ã— 9 ft

l = 153/9

l = 17 ft

Therefore the length of the studio is 17 feet.

Options:

a.

b.

c.

d.

Answer: c.

Explanation:

Given,

Mr. Patterson had a rectangular deck with an area of 112 square feet built in his backyard.

A = 28 ft Ã— 4 ft

A = 112 square feet

Thus the correct answer is option c.

Question 14.

The town indoor pool is in a rectangular building. Marco is laying tile around the rectangular pool. How many square meters of tile will Marco need?

Options:

a. 96 square meters

b. 252 square meters

c. 572 square meters

d. 892 square meters

Answer: 252 square meters

Explanation:

The outer rectangle is

l = 26 m

w = 22 m

Area of the rectangle = l Ã— w

A = 26 m Ã— 22 m

A = 572 square meters

The inner rectangle is

l = 20 m

w = 16 m

Area of the rectangle = l Ã— w

A = 20 m Ã— 16 m

A = 320 square meters

Thus the square meters of tile will Marco need is 572 – 320 = 252 square meters.

Question 15.

A drawing of a high school pool is shown below.

What is the area of the pool? Explain how you know.

_______ square yards

Answer:

Explanation:

Figure 1:

l = 10 yd

w = 15 yd

Area of the rectangle = l Ã— w

A = 10 yd Ã— 15 yd

A = 150 square yard

Figure 2:

l = 15 yd

w = 10 yd

Area of the rectangle = l Ã— w

A = 15 yd Ã— 10 yd

A = 150 square yard

Figure 3:

l = 10 yd

w = 5 yd

Area of the rectangle = l Ã— w

A = 10 yd Ã— 5 yd

A = 50 square yard

Area of the pool = 150 square yard + 150 square yard + 50 square yard = 350 square yard

Question 16.

Mr. Brown has 24 meters of fencing. He wants to build a rectangular pen for his rabbits.

Answer:

Question 16.

B. Find the area in square meters of each rabbit pen you made in Part A. Show your work.

Type below:

_________

Answer: 20 square meters

Explanation:

l = 10m

w = 2m

Area of the rectangle = l Ã— w

A = 10 m Ã— 2 m

A = 20 square meters

Therefore the area in square meters of each rabbit pen is 20 square meters.
