component of a rectangle = length x width by way of fact the fee varies at the same time with length and width, then it varies at the same time with the section. Or the fee is proportional with the section. subsequently, fee = ok x section, the place ok is a persevering with. From the 1st equation, 4 hundred = 8 x 10 x ok, fixing for ok = 4 hundred/80 = 5 Now examine with the 2d equation, 9 x 12 x 5 = 540 (appropriate). Now, fee of room 11 x 14 is 11 x 14 x 5 = $770

divide both sides by -3/5
r=1
-3/5r = -3/5
3/5r = 3/5
3 = 3r
r = 1
