Question

Reed wants to have a square garden plot in his backyard. He has enough compost to cover an area of 214 square feet. To the nearest tenth of a foot, how long can a side of his garden be?

Answer 1

14.6 feet

Explanation:

Let A be the area of a square and S be the length of one of its sides.

The area of a square is A = S². We know A = 214 in this problem, so:

214 = S²

√214 = S

S ≈ 14.629 ≈ 14.6 feet (to the nearest tenth of a foot)
