Question

The drawing shows a concrete walkway around a pool. what is the total area of the concrete?

Answer 1

Answer:

Hence, area of concrete is: 165 ft^2.

Hence, option: A is the correct answer.

Step-by-step explanation:

We have to find the total area of the concrete.

The area of concrete is given by:

Area of rectangle ( with dimensions 25 ft × 13 ft. )- Area of rectangle ( with dimensions 20 ft. × 8 ft. )

Hence,

Area of rectangle with dimensions 25 ft × 13 ft.  is

25×13=325 ft^2.

Also area of rectangle with dimensions  20 ft. × 8 ft. is:

20×8=160 ft^2.

Hence, area of concrete is calculated as:

325 ft^2-160 ft^2=165 ft^2.

Hence, option: A is the correct answer.

Hence, area of concrete is: 165 ft^2.

Answer 2

25 x 13 = 325

20x 8 = 160

325-160 = 165 square feet

 answer is A
