Answer: the length is 23 feet the width is 14 feet
Step-by-step explanation:
Let the length is x feet
Hence, the width is (x-9) feet
The perimeter of a rectangular pool is:
P=(2)(x+(x-9))
74=(2)*(2x-9)
74=(2)(2x)-(2)(9)
74=4x-18
74+18=4x-18+18
92=4x
(4)(23)=(4)(x)
Divide both parts of the equation by 4:
23 feet=x
23-9=x-9
14 feet=x-9
