Problema Solution
A National Hockey League rink is 115 feet longer than it is wide. If the perimeter of the rink is 570 feet, find the dimensions of the rink.
Answer provided by our tutors
let 'w' represent the width, then 'w+115' represents the length
perimeter = 2(l+w), where 'l' and 'w' represent length and width
570 = 2(w + w+115)
solving for 'w' we have w=85
85+115 = 200
the rink is 85 feet wide and 200 feet in length
