Question

4-8 tina’s rectangular living-room floor measures 15 feet by 18 feet.
a. how many square feet of carpet will tina need to cover the entire floor?
square feet = ______
b. the carpet tina likes is sold by the square yard. how many square yards will she need?
(1 yard = 3 feet)

Explanation:

Step1: Calculate the area in square feet

The area of a rectangle is calculated by the formula \(A = l\times w\), where \(l = 18\) feet and \(w=15\) feet.

$$A = 18\times15=270$$

Step2: Convert square feet to square yards

Since \(1\) yard \( = 3\) feet, \(1\) square yard \(=(3\times3)\) square feet \( = 9\) square feet.
Let \(x\) be the area in square yards. Then \(x=\frac{270}{9}\)

$$x = 30$$

Answer:

a. \(270\) square feet
b. \(30\) square yards
