Problema Solution
The length of a rectangle is 2 more than the width and the perimeter is 80. Find the dimensions of the rectangle.
Answer provided by our tutors
let
l = the length of the rectangle
w = the width of the rectangle
the length of a rectangle is 2 more than the width:
l = 2 + w
the perimeter is 80:
2(l + w) = 80
by solving the system of equations:
l = 2 + w
2(l + w) = 80
we find:
l = 21
w = 19
