The length of hockey rink is 200 feet and width of hockey rink is 85 feet.
Step-by-step explanation:
Given,
Perimeter of hockey rink = 570 feet
Width of hockey rink = w
Length of hockey rink = w+115
As a hockey rink is in rectangular shape;
Perimeter of rink = 2(Length + Width)

Dividing both sides by 4

Width of hockey rink = 85 feet
Length of hockey rink = 85+115 = 200 feet
The length of hockey rink is 200 feet and width of hockey rink is 85 feet.
