Question

A rectangular swimming pool is 40 feet long and 20 feet wide. The pool is bordered by square tiles that are x feet in length surrounding the pool. Write an expression that represents the longest side of the pool and the tile border.

Answer 1

`(40+2x)\ ft`

Explanation:

we know that

The length of the rectangular swimming pool is equal to

L=40 ft

The square tiles are x feet in length surrounding the pool

so

The longest side of the pool and the tile border is equal to the sum of the length of the swimming pool plus two times the wide of the square tiles

`(40+2x)\ ft`
