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
