Us plans to install a handrail around a rectangular skating rink. One of the rink's sides is 40 meters long and one of the rink's width is 20 meters wide. How many meters of handrail does Gus need to cover the perimeter of the rectangular skating rink?

Given :

Length of rink, L = 40 meters.

Width of rink , W = 20 meters.

To Find :

How many meters of handrail does Gus need to cover the perimeter of the rectangular skating rink.

Solution :

We know, perimeter is given by :

Putting value of L = 40 meters and W = 20 meters, in above equation , we get:

Therefore, the perimeter of the rectangular skating rink is 120 meters.

Hence, this is the required solution.
