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
