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 :

2/3 x  * x = 864
(2/3) x^2 = 864
x^2 = 864 * (3/2) =  1296
x = + sqrt 1296  = 36

length is 36 feet
