Problema Solution
The length of a rectangle is 3 inches more than twice its width. Its perimeter is 48 inches. Find the dimensions. |
Answer provided by our tutors
let
l = the length of the rectangle
w = the width of the rectangle
P = 48 in the perimeter of the rectangle
the length of a rectangle is 3 inches more than twice its width
l = 3 + 2w
the formula for the perimeter of the rectangle is P = 2(l + w)
2(l + w) = 48 divide both sides by 2
l + w = 24
by solving the system of equations
l = 3 + 2w
l + w = 24
we find
l = 17 in
w = 7 in
