Problema Solution
The length of a rectangle is 7 times ( 1 less than the width). The perimeter is 50. Find the width
Answer provided by our tutors
let
l = the length
w = the width
the length is 7 times (the width less than 1)
l = 7*(w - 1)
the perimeter is 50
2(l + w) = 50
l + w = 25
by solving the system of equations
l = 7*(w - 1)
l + w = 25
we find
l = 21
w = 4
