If the ratio of the measures of the length and width of a rectangle is 3:2, then there exists a real number 
such that the length is equal to 
and the width is equal to 
Using the formula for the perimeter:
and substituting what we know about the length and width:
\ +\ 2(2k)\ =\ 55)
Solve for , then multiply by 3 to get the length and by 2 to get the width.
