Math Problem Statement

You want to install wall-to-wall carpeting in the family room. The floor plan is shown.

7 ft

10 ft

11 ft

11 ft

A floor plan consists of two rectangles. The right edge of the first, smaller rectangle is joined to the left edge of the second, larger rectangle. There are four measurements.

The top edge of the smaller rectangle is 7 ft.

The left edge of the smaller rectangle is 10 ft.

The top edge of the larger rectangle is 11 ft.

The right edge of the larger rectangle is 11 ft.

If the cost of the carpet you would like to purchase is $33 per square yard, what is the cost (in dollars) of carpeting your family room? Assume that there is no waste. Hint:

9 ft2 = 1 yd2.

(Round your answer to the nearest cent.)
