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

A = a^2where " a " is the length of one side
A = 79

79 = a^2...take sqrt of both sides, eliminating the ^2
sqrt 79 = a
8.89 = a

so the length of one side is approximately 8.89 ft <==
