Problema Solution
The ratio of the width to the length of a rectangle is 2:3. If the area of the rectangle is 216 sq cm, what is its width?
Answer provided by our tutors
let 'w' represent the width, then '(3/2)w' represents the length
area = l*w, where 'l' and 'w' represent length and width, respectively
216 = w(3/2)w
solving for 'w' we have a positive value of w=12
the width of the rectangle is 12 cm
