Problema Solution

The perimeter of a rectangle is 36 m. The length is 2 m more than three times the width. Find the length and the width of the rectangle.

Answer provided by our tutors

let 'w' represent the width, then '3w+2' represents the length


perimeter = 2(length + width)


36 = 2(w + 3w+2)

36 = 8w + 4

w = 32/8 = 4


3*4+2 = 14


the width is 4 m, the length is 14 m
