Question

#9 part A

George wants to put carpeting in a rectangular living room and a square bedroom. The length and width of the living room is 12 feet by 18 feet. One side of the square bedroom is 13 feet. It will cost $3.50 per square foot to carpet the rooms. Write an expression that can be used to find the total amount George will pay for carpeting.

Answer 1

Cost = [(18×12) + (13×13)] × 3.50

Explanation:

The total cost will depend on the area of the living room and the area of the bedroom.

For the living room,

Area 1 = l×w

Area 1 = 18 × 12

For the bedroom,

Area 2 =13 × 13

Total area = (18×12) + (13×13)

The total cost is the area times the cost per square foot.

Cost = [(18×12) + (13×13)] × 3.50

George can use this expression to find the cost of the carpeting.
