Question

Andy used a scale of inch = 2 feet for a drawing of his house. On the

2
drawing, a rectangular room measures 3 inches by 2 inches. Andy
wants to purchase new carpet for the room that costs $4.89 per square
foot. Before sales tax, how much will the new carpet cost?

Answer 1

$117.36

Explanation:

The room is 3 by 2 inches, so to convert this to feet you need to multiply both by 2. This is because the scale is one inch equals two feet.

3 x 2 = 6

2 x 2 = 4

The room is 6 by 4 feet. Find the Area of the room by multiplying these two numbers together

6 x 4 = 24

The room is 24 ft^2. If the carpet costs $4.89 per square foot, just multiply the cost by the area of the room.

24 x 4.89 = 117.36

The cost to carpet the room is $117.36
