Question

A square rug covers 79 square feet of floor. What is the approximate length of one side of the rug? (Approximate to the nearest hundredth foot.)

Answer 1

8.89 ft

Explanation:

Answer 2

A = a^2.....the Area (A) of a square = a^2...where a = one side

79 = a^2...now take the sqrt of both sides, this eliminates the ^2
sqrt 79 = a
8.888 rounded = 8.89 = a......so one side = 8.89 ft
