This could be solved symbolically first, but then you might not see quickly if the resulting quadratic equation is factorable.

x = length
y = width
x = 5y
xy=125 meaning %285y%29y=125

This example is easier to solve directly with the given values and not in pure symbolic form.

5y%5E2=125
y%5E2=125%2F5
y%5E2=25
y=5----- the width
25=x----- the length
