Problema Solution
The length of a rectangle is 2 meters less than 3 times the width. The perimeter is 20 meters. Find the width
Answer provided by our tutors
let 'w' represent the width in meters, then '3w-2' represents the length in meters
perimeter = 2(length + width)
20 = 2(w + 3w-2)
20 = 8w - 4
w = 24/8 = 3
3*3-2 = 7
the width is 3 meters, the length is 7 meters
