Question

A square sign has an area of approximately 158 feet .What is the approximate length of one side of the sign?

Answer 1

12.5698 (approximately 12.5, rounding to the nearest half)

Explanation:

The area of a square is represented by the following equation:

`A=a^2`

Whereas "a" represents the length of any one of the sides.

Since all sides of a square are equal in length, we can reverse engineer this formula to find the length of one side.

`158=a^2`

Simply take the square root of both sides and you will have your answer.

`12.5698=a`
