Question

You want to carpet three rooms of a house. The dimensions are shown in the drawing.

If the carpet sells for $12.85 per square yard, what will be the cost?

Answer 1

$976.60

Explanation:

First we find the area of each room. Each room is rectangular; this means to find the area we multiply the length and width:

16(20) = 320 sq. ft.

14(12) = 168 sq. ft.

14(14) = 196 sq. ft.

This is a total area of 320+168+196 = 684 sq. ft.

The carpet is sold in square yards. 1 square yard is a square whose sides are 1 yard by 1 yard; this is the same as a square whose sides are 3 feet by 3 feet. This gives us an area of 9 square feet; this means 1 square yard is equal to 9 square feet.

This gives us 684/9 = 76 sq. yd.

Each square yard of carpet is $12.85; this gives us a cost of

76(12.85) = $976.60
