Alright. We got a rectangle that is times greater than its width. Let's say width is w, ok? (We're using w as a variable) then length will be , right? We will going to put it into an equation of which . Well obviously . Sooo . Remember the reciprocal? We're going to multiply on each side, so that the equation will be . . Multiply across. It'll equal , and when you simplify, it'll equal 36 if you did it right. Now the equation comes down to . , right? So w will be 6.
We're not done yet. w = 6, but that's only the width. equals , which is 8. So width is 6 and length is 8.
