Question

the diagram below shows an 18 foot by 40 foot pool surrounded by a 4 foot wide walkway what is the area of the walkway?

Answer 1

248 sq. ft

Explanation:

One method to solve this is:

Find the area of the pool by multiplying the width by the length, then add the width of the walkway and find the total area. And finally subtract the first product from the second to isolate the area of just the walkway.

So...

18 x 40 = 720

18 + 4 = 22 and 40 + 4 = 44

22 x 44 = 968

968 - 720 = 248
