Question

A square garden has an area of 103 square feet. . . . To the nearest tenth, what is the length of one side of the garden?. . A.. 51.5 feet. . B.. 25.8 feet. . C.. 10.1 feet. . D.. 7.2 feet.

Answer 1

A = a^2......Area = a (one side) ^2

103 = a^2.....take the sqrt of both sides, eliminating the ^2
sqrt 103 = a
10.1 ft <==

Answer 2

A = 103 ft²;
A = l²
l² = 103
l = √ 103 = 10.14889 ≈ 10.1
Answer: C ) 10.1 feet
