Problema Solution
the length of a rectangle is 10 Centimeters less than its width. what are the dimensions of the rectangle if its area is 144 square centimeters.?
Answer provided by our tutors
let
l = the length of the rectangle, l>0
w = the width of the rectangle, w>0
the length of a rectangle is 10 centimeters less than its width
l = w - 10
the area is 144 centimeters
l*w = 144
plug l = w - 10 into the last equation
(w - 10)*w =144
by solving we find
w = 18 cm
click here to see the step by step solution of the quadratic equation
l = 18 - 10
l = 8 cm
the width is 18 cm.
the length is 8 cm.
