Question 333119: The ratio of the sides of a particular rectangle are 3:2. What is the length of each side if the perimeter of the rectangle is 55 cm? Answer by solver91311(24713) (Show Source):
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:
Solve for , then multiply by 3 to get the length and by 2 to get the width.
