Question

The length of the rectangular swimming pool is one foot less than twice the width. The perimeter of the pool is 112 feet. Find the length of the pool.

Answer 1

length is 19 ft

Explanation:

b = length, we can write the formula for perimeter and plug in the width

112= 2a + 2b

112= 2(2b-1)+ 2b

112= 4b -2 +2b

114 = 6b

b= 19
