Question

Renee wants to put a fence around her

square garden that has an area of

6,500 square feet. Determine the

perimeter of the garden to the nearest

tenth of a foot.

Answer 1

perimeter = 322.5 ft ( to the nearest tenth of a foot)

Explanation:

Length the length of the sides of the square be L

Area of a square = L²

∴ 6,500 = L²

L = √(6,500)

L = 80.6226

Next Let us calculate the perimeter

Perimeter of a square = L + L + L + L = 4L

perimeter = 4 × 80.6226

Perimeter = 322.4904 ft

perimeter = 322.5 ft ( to the nearest tenth of a foot)

N:B rounding to the nearest tenth of a foot is same as rounding to 1 decimal place.
