The perimeter of a rectangle is 66 cm and it’s width is half of its length. What are the length and the width of the rectangle?

Question

It is asking for the length and width 

 

Answer 1

First, it's should be its.  (It's is a contraction, meaning IT IS.)

 

Let width = x, so length must be 2x.  Add up the four sides; 6x = 11, right?

 

Length 22 cm, width 11 cm.  GOLLY, THAT WAS EASY, using the given facts and ALGEBRA!
