what is the smallies peramiter of 64

Question

A backyard has an area of 64 square feet. What is the smallest possible perimeter of the backyard?

Answer 1

If the choices are restricted to polygons, it is a square with side sides of 8 ft., perimeter is 32 ft.

If the choices include curved figures it is a circle.

64 = πr²

20.37 ≈ r²

4.51 ≈ r

C = 2πr

C = 2π(4.51)

C = 28.3 ft.
