Problema Solution
A certain rectangle is 3 cm longer than it is wide. The area of the rectangle is 550 cm (squared). Find the dimensions of the rectangle.
Answer provided by our tutors
width = w
length = w +3
area = length * width = 550
w (w+3) = 550
w^2 + 3 w - 550 = 0
solving
we get
w = 22
width = 22 cm
length = 25 cm
