If Mr. arenth wants to put new carpeting in the room shown, how many square feet should he order L = 14ft. W = 6c-8ft. L = 5+3c ft.

If you put 5+3c=14 and solve you will get c=3 so then you put 3 in for c for the width equation. you then get 10 ft for the width. if you multiply 10 ft by 14 ft you would get the answer of 140 sq ft
