You can put this solution on YOUR website! the perimeter of a large rectangular room measures 900 ft. the surface area of its floor is found to be 50000sq.ft how long is each side of the store room?
L*W = 50000
l= 50000/W
Perimeter = 2L+2W
900 = 2* 50000/w + 2w
900= 100000 +2w^2 / w
900w= 100000 +2w^2
2w^2-900w+100000
w^2-450w+50000 =0
w^2-250w-200w +50000=0
w(w-250)-200(w-250)=0
(w-200)(w-250) =0
w= 200 or 250 feet
