Calculating Perimeter of Shapes

The video tutorial explores the concept of perimeter, starting with a rectangle example where all sides are labeled and added to find the perimeter. It then moves to a problem where the perimeter is given, and the task is to find missing side lengths using subtraction and division. Finally, the tutorial covers calculating the perimeter of a square, emphasizing that all sides are equal. The video provides a step-by-step approach to understanding and solving perimeter-related problems.

What does the term 'perimeter' refer to in geometry?

• The area inside a shape

• The distance around a shape

• The volume of a shape

• The diagonal of a shape

How do you calculate the perimeter of a rectangle?

• Multiply the length by the width

• Divide the length by the width

• Add all the side lengths together

• Subtract the width from the length

What is the perimeter of a rectangle with sides 10 cm and 6 cm?

• 26 cm

• 32 cm

• 36 cm

• 40 cm

If a rectangle has sides of 6 cm and 10 cm, what is its perimeter?

• 40 cm

• 32 cm

• 22 cm

• 16 cm

In a rectangle with a given perimeter of 24 feet, if one side is 3 feet, what is the length of the other side?

• 12 feet

• 9 feet

• 15 feet

• 6 feet

What is the first step in finding missing side lengths when the perimeter is known?

• Subtract the known side from the perimeter

• Multiply the known side by 2

• Divide the perimeter by 4

• Fill in the known side lengths

After subtracting the known sides from the perimeter, what is the next step?

• Subtract the result from the known sides

• Multiply the result by 2

• Divide the result by 2

• Add the result to the known sides

If a rectangle's perimeter is 24 feet and one side is 3 feet, what is the total length of the other two sides?

• 20 feet

• 12 feet

• 18 feet

• 24 feet

Which of the following is NOT a step in finding the missing side lengths of a rectangle?

• Fill in known sides

• Multiply the perimeter by 2

• Divide the result by 2

• Subtract known sides from perimeter

What is the perimeter of a rectangle with sides 9 feet and 3 feet?

• 30 feet

• 36 feet

• 24 feet

• 18 feet
