Expression: 3.5 ((12x18) + 13²)

Step-by-step explanation:

Since George is going to put carpeting in two different rooms, one rectangular and one square, you need to find the area of each room, add the sum and then multiply the total area needed by the cost per square foot of carpet. The area of a rectangle is: a = lw, where l=length and w = width. The area of a square is: a = s², where s = side of the square. Take the sum of these two areas would be (12 x 18) + 13² or 213 + 169 = 382. Since the cost of the carpet is the same per square foot, you can multiply the entire sum by the cost of $3.50 or: 3.5 ((12 x 18) + 13²) or 3.5 (382) = $1,337.
