Calculating Rectangle Perimeters

The video tutorial explains how to calculate the missing side of a geometric figure given its perimeter. It starts with a figure having a perimeter of 24 centimeters and demonstrates how to find the missing side by adding the known sides and subtracting from the total perimeter. The tutorial then moves on to a rectangle with a perimeter of 32 meters, where one side is known, and the opposite sides are equal. The process involves calculating the remaining sides to ensure the total perimeter is correct.

What is the perimeter of a shape?

• The diagonal length of the shape

• The volume of the shape

• The distance around the outside of the shape

• The area inside the shape

If a figure has a perimeter of 24 cm and three sides are 6 cm, 5 cm, and 4 cm, what is the length of the missing side?

• 7 cm

• 8 cm

• 5 cm

• 6 cm

What is the sum of the known sides in the first example?

• 15 cm

• 24 cm

• 20 cm

• 19 cm

In a rectangle, if one side is 11 meters, what can be said about the opposite side?

• It is half the length

• It is equal in length

• It is unrelated in length

• It is double the length

A rectangle has a perimeter of 32 meters and one side is 11 meters. What is the length of the other pair of sides?

• 8 meters

• 5 meters

• 6 meters

• 7 meters

How do you calculate the missing side length in a rectangle if you know the perimeter and one side length?

• Subtract the known side from the perimeter

• Add the known side to the perimeter

• Divide the perimeter by 4

• Subtract twice the known side from the perimeter and divide by 2

In the rectangle example, what is the total length of the known sides?

• 11 meters

• 44 meters

• 22 meters

• 32 meters

What is the first step in finding the missing side of a rectangle?

• Divide the perimeter by 2

• Subtract the known sides from the perimeter

• Multiply the known side by 2

• Add all sides together

If a rectangle's perimeter is 32 meters and one side is 11 meters, what is the perimeter of the remaining sides?

• 12 meters

• 11 meters

• 22 meters

• 10 meters

What is the final step in calculating the missing side length in the rectangle example?

• Add the known side to the perimeter

• Multiply the remaining length by 2

• Divide the remaining length by 2

• Subtract the known side from the perimeter
