#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.

Cost = [(18×12) + (13×13)] × 3.50

Step-by-step 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.
