Problema Solution
Find the width and the length of a rectangle,if length is 4 meters less than 3 times the width,and the perimeter is 16
Answer provided by our tutors
let
l = the length of the rectangle, l>0
w = the width of the rectangle, w>0
length is 4 meters less than 3 times the width
l = 3w - 4
the perimeter is 16:
2(l + w) = 16
by solving the system of equations:
l = 3w - 4
2(l + w) = 16
we find:
l = 5
w = 3
