Problema Solution
The lenght of a rectangular boat storage must be four meters more than the width and the perimeter must be at least 128 meters.What is the range of the values for the width?
Answer provided by our tutors
let 'w' represent the minimum width in meters, then 'w+4' represents the length
perimeter = 2(l+w), where 'l' and 'w' represent length and width, respectively
128 <= 2(w+w+4)
solving we have:
x >= 30
the width must be at least 30 meters
