Problema Solution
The length of a rectangle is 3 meters longer than its width.
If the perimeter of the rectangle is 34 meters , find its area.
Answer provided by our tutors
let
l = the length of the rectangle
w= the width of the rectangle
the length of a rectangle is 3 meters longer than its width
l = 3 + w
the perimeter of the rectangle is 34 meters
2(l + w) = 34
by solving the system of equations
l = 3 + w
2(l + w) = 34
we find
l = 10 m
w = 7 m

the area A = l*w
A = 10*7
A = 70 m^2
