Problema Solution
The length of a rectangle is 3 ft less than double the width, and the area of the rectangle is 44ft^2 . Find the dimensions of the rectangle.
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 3 ft less than double the width
l = 2w - 3
the area of the rectangle is 44ft^2
l*w = 44
plug l = 2w - 3 into l*w = 44
(2w - 3)*w = 44
by solving we find
w = 5.5 ft

l = 2*5.5 - 3
l = 8 ft
the length of the rectangle is 8 ft, while the width is 5.5 ft.
