The length of a rectangular swimming pool is 4 meters more than 4 times its width.
The perimeter of the pool is 248 meters.
What are the length and width of the pool?
:
The perimeter
2L + 2W = 248
simplify, divide by 2
L + W = 124
:
It says,"length is 4 meters more than 4 times its width." so we can say
L = 4W + 4
:
Replace L with (4W+4) in the simplified perimeter equation, find W:
(4W+4) + W = 124
5W = 124 - 4
5W = 120
W =
W = 24 m is the width
:
I'll let you find L by using the equation L = 4W + 4
:
Then check the solutions in the original perimeter equation
