Question

Jackson is comparing two squares. The first square has an area of 64 cm2. The second square has an area of 121 cm2. What is the difference in the perimeters of the two squares in centimeters?

Answer 1

12 cm difference

Explanation:

√64 cm² = 8 cm

8 cm x 4 = 32 cm perimeter

√121 cm² = 11 cm

11 cm x 4 = 44 cm perimeter

44 cm - 32 cm = 12 cm difference
