Question

1. the perimeter of a square room is 80 feet. how many floor tiles square would be needed to cover the area of the room?

Explanation:

Step1: Find the side length of the square

The perimeter formula of a square is \(P = 4s\), where \(P\) is the perimeter and \(s\) is the side - length. Given \(P=80\) feet. Then \(s=\frac{P}{4}\).

$$s=\frac{80}{4}=20$$

feet.

Step2: Calculate the area of the square

The area formula of a square is \(A = s^{2}\). Substitute \(s = 20\) into the formula.

$$A=20\times20 = 400$$

square feet.

Assume each floor - tile is \(1\) square foot.

Answer:

400
