Problema Solution
The perimeter of a rectangular is 210 and the length is 3 less than 3 times the width, find the dimensions
Answer provided by our tutors
let 'w' represent the width, then '3w-3' represents the length
perimeter = 2(length + width)
210 = 2(w + 3w-3)
210 = 8w - 6
x = 216 / 8
x = 27
3*27 - 3 = 78
the width is 27, the length is 78
