Understanding Perimeter Calculation for a Skating Rink

Gus needs to install a handrail around a rectangular skating rink. The rink measures 40 meters by 20 meters. To determine the total length of handrail required, we calculate the perimeter of the rectangle. Since opposite sides of a rectangle are equal, the perimeter is the sum of all sides: 40 + 20 + 40 + 20, totaling 120 meters. Thus, Gus needs 120 meters of handrail to cover the entire perimeter of the rink.

What is the shape of the skating rink Gus is planning to install a handrail around?

• Rectangle

• Square

• Triangle

• Circle

What are the dimensions of the skating rink?

• 60 meters by 30 meters

• 50 meters by 25 meters

• 40 meters by 20 meters

• 30 meters by 10 meters

Why does Gus need to install handrails on all sides of the rink?

• To ensure safety for skaters

• To prevent people from entering

• To decorate the rink

• To mark the boundary

If one side of the rectangle is 40 meters, what is the length of the opposite side?

• 50 meters

• 30 meters

• 20 meters

• 40 meters

How do you calculate the perimeter of a rectangle?

• Add all the side lengths together

• Add the length and width, then multiply by two

• Multiply the length by the width

• Multiply all side lengths together

If the length of the rink is 40 meters, what is the total length of the two longer sides?

• 40 meters

• 80 meters

• 60 meters

• 100 meters

What is the total length of the two shorter sides of the rink?

• 40 meters

• 60 meters

• 20 meters

• 80 meters

What is the total length of handrail Gus needs to install around the rink?

• 100 meters

• 110 meters

• 120 meters

• 130 meters

What is the purpose of calculating the perimeter in this context?

• To find out how much handrail is needed

• To determine the area of the rink

• To measure the height of the rink

• To calculate the volume of the rink

What is the perimeter of a rectangle with sides 40 meters and 20 meters?

• 130 meters

• 120 meters

• 110 meters

• 100 meters
