Question

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

Answer 1

Answer:

12.5698 (approximately 12.5, rounding to the nearest half)

Step-by-step 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.

$12.5698=a$
