Multi-Step Jorge sews a trim around the edge of a tablecloth with 8 sides. He has 32 feet of trim. If each side of the tablecloth is 2 feet long, how much trim will Jorge have left?
(A) 10 feet
(B) 8 feet
(C) 42 feet
(D) 16 feet
Answer:
D. 16 feet

Explanation:
Jorge sews a trim around the edge of a tablecloth with 8 sides, each side of the tablecloth is 2 feet long.
Perimeter of any figure is length of side multiplied by number of sides of the figure
Then perimeter of the table cloth is 8 x 2 = 16
Jorge has 32 feet of trim
Subtract 16 from 32
32-16=16 feet
Therefore, jorge left 16 feet of trim.
