A rectangle that is the ratio of length to width is 3:2. If the area is 125cm^2 what are the lengths of the sides?
---------
3:2 is the same as 3x:2x where 3x is length and 2x is width.
---------
Equation::
(3x)(2x) = 125 cm^2
-----
6x^2 = 125
x^2 = 20.8333..
====
x = 4.5644..
----
length = 3x = 13.69 cm
----
width = 2x = 9.13
