Problema Solution
The length of a rectangle is 4 inches more than 2 times the width. The perimeter is 50 inches. Find the length and the width.
Answer provided by our tutors
let
l = the length of the rectangle
w = the width of the rectangle
the length of a rectangle is 4 inches more than 2 times the width
l = 4 + 2w
the perimeter is 50 inches
2(l + w) = 50 divide both sides by 2
l + w = 25
by solving the system of equations
l = 4 + 2w
l + w = 25
we find
l = 18 in
w = 7 in
