The width of a rectangle is three less than the length. if the area of the rectangle is 88 square cm, find the dimensions of the rectangle

Let the length be l

Then,

l * (l-3) = 88

l²-3l = 88

l²-3l-88=0

l²-11l + 8l - 88 = 0

l (l-11) + 8 (l-11) = 0

(l+8) (l-11) = 0

As, l can't be negative, length=11cm and width = (l-3) = 11-3 = 8 cm
