The Turners want to install outdoor carpet around their rectangular pool. The dimensions for the rectangular area formed by the pool and its walkway are 20 ft by 30 ft. The pool is 12 ft by 24 ft.a) How many square feet need to be covered?b) Approximately how many square yards does the area in part (a) represent?c) If the carpet costs \$12.95 per square yard, what will be the cost of the carpet?

To determine

(a)

To find:

The number of square feet need to be covered.

Explanation

Theorem:

The area A of a rectangle whose base has length b and whose altitude has length h is given by A=bh

Calculation:

Given:

The dimensions for the rectangular area formed by the pool and its walkway are 20 ft by 30 ft. The pool is 12 ft by 24 ft.

Suppose that cement around rectangular pool is covered by carpet.

Sketch the rectangular pool as shown below:

To find how many square feet need to be covered:

The area A of a rectangle A=bh.

To determine

(b)

To find:

Number of square yards the area in part (a) represents approximately.

To determine

(c)

To find:

The cost of the carpet.
