Louis wants to carpet the rectangular floor of his basement. The basement has an area of 864 square feet. The width of the basement is 2/3 its length. What is the length of Louis's basement.

Respuesta :

Area=Lenght*width.
Then, 864=Lenght*(2/3)*lenght
=> lenght= sqrt(864*3/2)
=> lenght= sqrt(1296) = 36.
