Problema Solution
a rectangle is drawn so that the width is 3 feet shorter than the length. the area of the rectangle is 28 square feet. find the length 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 width is 3 feet shorter than the length:
w = l - 3
the area of the rectangle is 28 square feet:
l*w = 28
plug w = l - 3 into the last equation:
l*(l - 3) = 28
by solving we find:
l = 7 ft
