Question

A square rug has an area of 256 square feet. What is the perimeter of the rug?

Answer 1

Answer: 8ft

Explanation:

4A= 256

4A/4 = 256/4

A = 64

A = a²

64 = 4²

a² = 64

a = ±√64

a = ±8

∴a = ±8

Hence, the length of a side of each rug is 8ft.

Answer 2

64

Explanation:

`√(256)` = 16 (length of each side)

A square (rug) has 4 sides.

Add to find perimeter:

16 + 16 + 16 + 16

= 64
