Question

Suzanne wants to put a fence around her square garden. If the garden covers an area of 64 ft^2, how many feet of fencing does she need? Area = length x width and length =width

Answer 1

32 feet of fence

Explanation:

The garden is a square, so the length and width are equal.

A = L x W

W = L

A = W²

A = 64

W² = 64

W = √64 = ±8 -- (-8) would be extraneous

W = 8 ft

L = 8ft

Since she is putting the fence around the garden, she needs to find the perimeter.

P = 2L + 2W

P = 2(8) + 2(8)

P = 16 + 16

P = 32 ft

32 feet of fence
