<PRE><B>Question 169853</B>
    The perimeter of a swimming pool is 96 meters. The width is 3 meters more that the length of the pool. Find the length and width of the pool.
.
Let x = length of the pool
then
x+3 = width of the pool
.
Remember, the perimeter of any rectangle is:
W + W + L + L
2W + 2L
2(W + L)
.
So, rewriting the above with our variable we have:
96 = 2(x + x+3)
96 = 2(2x+3)
96 = 4x+6
90 = 4x
22.5 meters = x (length of pool)
.
width:
x+3 = 22.5+3 = 25.5 meters (width of pool)
