Alice wants to put wall-to-wall carpeting in a small room with the floor plan shown. a. How much will Alice pay for carpet that costs $4.50 per square foot? b.

If you would like to know how much will Alice pay for carpet that costs $4.50 per square foot, you can calculate this using the following steps:

First, we have to find the area of the room by dividing the floor plan into two rectangles.

Calculating the area of the rectangle: multiplying the length with the width.

a ... area

l ... length

w ... width

First rectangle:

a1 = l * w = 7.5 ft * 5 ft = 37.5 square ft

Second rectangle:

a2 = l * w = 7.5 ft * 10 ft = 75 square ft

a = a1 + a2 = 37.5 + 75 = 112.5 square ft

Cost of the carpet: $4.50 per square foot

$4.50 per square foot * 112.5 square ft = 4.50 * 112.5 = $506.25

The correct result would be $506.25.
