H.O.T. Multi-Step Alii had some craft sticks. She decided to make shapes. If she used one craft stick for each side of the shape, would Alii use more craft sticks for 5 squares or 6 triangles? Explain.

Answer:
Alii use 2 more craft sticks for 5 squares than 6 triangles.

Explanation:
Number of craft stick for each side of the shape she used = 1.
Number of sides for a square = 4.
Number of craft sticks for making 5 squares = 5 × (Number of craft stick for each side of the shape she used × Number of sides for a square)
= 5 × (1 × 4)
= 5 × 4
= 4 × 4 + 4
= 16 + 4
= 20.
Number of sides for a triangle = 3.
Number of craft sticks for making 6 triangle = 6 × (Number of craft stick for each side of the shape she used × Number of sides for a triangle)
= 6 × (1 × 3)
= 6 × 3
= 18.
Difference:
Number of craft sticks for making 5 squares – Number of craft sticks for making 6 triangle
= 20 – 18
= 2.
