Question

A rectangle is twice as long as it is wide. Its perimeter is (the sum of the lengths of its sides) is 60cm.Find the length and width.

Answer 1

Let width = x

Let length = 2x

 

Use the variables to set up the equation to represent perimeter.

 

2x + 2(2x) = 60

 

 

Solve for x from this equation.
