Understanding Perimeter Concepts

The video tutorial introduces the concept of perimeter, using a Jurassic Park analogy to explain it as the boundary around a shape. It differentiates perimeter from area and provides a step-by-step guide to calculating perimeter using square units. Examples of perimeter calculation for different shapes are demonstrated, and alternative methods for calculating perimeter without squares are discussed. The video concludes with practice exercises for viewers to apply their learning.

What is the perimeter of a shape?

• The distance around the outside of a shape

• The diagonal of a shape

• The volume of a shape

• The area inside a shape

Which movie was used as an analogy to explain perimeter?

• Harry Potter

• The Matrix

• Jurassic Park

• Star Wars

What is the difference between perimeter and area?

• Perimeter is the outside, area is the inside

• Perimeter is the diagonal, area is the perimeter

• Perimeter is the inside, area is the outside

• Perimeter is the volume, area is the surface

How do you calculate the perimeter of a shape using squares?

• Count the squares around the shape

• Multiply the number of squares by two

• Subtract the squares from the total area

• Add the squares inside the shape

• 21 centimeters

• 14 centimeters

• 7 centimeters

• 28 centimeters

What is the perimeter of shape B if it has 14 squares around it?

• 12 squares

• 10 squares

• 14 squares

What is the perimeter of shape C?

• 16 centimeters

• 12 centimeters

• 14 centimeters

• 10 centimeters

How can you calculate perimeter without counting squares?

• By dividing the lengths of labeled sides

• By multiplying the lengths of labeled sides

• By subtracting the lengths of labeled sides

• By adding the lengths of labeled sides

If a side is labeled 3 cm and another is 4 cm, what is the perimeter of a rectangle?

• 10 centimeters
