Write an equation to find the area of the garden.

Question

Lisa sections off a rectangular region in her backyard for a small garden. The length is 2 feet less than twice the width. Write an equation to find the area of the garden. 

Answer 1

Let width = w

Let length = 2w - 2

 

You know the area of a rectangle is length times width.  Use that fact, along with the variables, to write the formula for area in terms of w.
