Question

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. feet feet feet feet

Answer 1

Answer:

2$\sqrt{30}$

Explanation:

As the room is square and the carpet is for the room, we can say that the carpet is square.

Let the side of the square carpet be L.

Given: Area of square carpet = 120 sq. ft.

As area of square = $L^{2}$

Therefore:

$L^{2}$ = 120 sq. ft.

Taking square root on both sides

L = $\sqrt{120}$ = 2$\sqrt{30}$ ft.
