The perimeter of a rectangle is less than 70 ft the length of the rectangle is 5 ft longer than its width ,, write an equation representing the length (L=length

Question

I need to write an equation representing the length ( L = Length) of the rectangle in terms of its width

Answer 1

Hi Jennifer,

 

The length is 5 ft longer than the width --> L = W + 5 . . . that's one equation that describes length in terms of width.

 

The perimeter is twice the length + twice the width --> 70 = 2L + 2W

 

Subtracting 2W from both sides--> 70 - 2W = 2L

 

Divide both sides by 2--> 35 - W = L . . . that's another equation that describes length in terms of width.
