Problema Solution
the width of a rectangle is 2 feet less than the length. the area of the rectangle is 24 square feet. find the length and the width
Answer provided by our tutors
let
l = the length of the rectangle, l>0
w = the width of the rectangle, w>0
the width of a rectangle is 2 feet less than the length
w = l - 2
the area of the rectangle is 24 square feet
l*w = 24
plug w = l - 2 into the last equation
l*(l - 2) = 24
by solving we find
l = 6 ft
click here to see the step by step solution of the equation
w = 6 - 2
w = 4 ft
the length of the rectangle is 6 feet.
the width of the rectangle is 4 feet.
