Question

Louis wants to carpet the rectangular floor of his basement. The basement has a area of 768 square feet. The width of the basement is 1/3 it’s length. What is the length of Louis’s basement

Answer 1

Area=width*length. Let width=x ft, then length=3x ft, given the information in the problem. The area of basement=x*3x=768, 3x^2=768, x^2=256, x=16. The width is 16 feet. Therefore, length=3x=3*16=48 feet.
