Question

A swimming pool in the shape of a rectangle is surrounded by 3 feet of walkway. the pool is 23 feet wide and 32 feet long. how long would the fence be that just encloses the walkway and the pool?

Answer 1

Dimensions of walkway and pool= (23+3) x (32+3) => 26ft x 35 ft 

Perimeter: 2(l+w) 
= 2 (26ft + 35ft) 
= 122 ft fence would be required to enclose the walkway and the pool.
