Question

The area of a square is given by A=s2, where s is the length of each side of the square. If the area of a square room is 81 square meters, what is the length of one side of the room in meters?

Answer 1

Answer: The length of one side is 9m.

Explanation:

If area is 81 square meters, that means A = 81 m^2.

Since A = s^2, we can substitute s^2 for A. Then

(s^2) = 81 m^2

Take the square root of both sides to solve for s:

(s^2)^(1/2) = (81 m^2)^(1/2)

s = 9 m
