Sandra bought 120 square feet of carpet for a room in her new house. If the room is square, what is the length of each side of the room?

Recall that the area of a square is calculated by l2, where l is the length of one side.

Answer:

length of each side of the room is 2√30 which is approximately 10.9545 feet

Explanation:

The area of the square can be computed as follows:

Area = l²

where l is the length of the side

We are given that:

area = 120 ft²

Substitute with the area in the above equation and solve for l as follows:

area = l²

120 = l²

l = √120

l = 2√30 ft

This is approximately equal to 10.9545 ft

Hope this helps :)
