Understanding Perimeter

The video tutorial introduces the concept of perimeter using a rectangular block and a star-shaped polygon. It explains how to calculate the perimeter by summing the lengths of all sides. The tutorial provides examples with a rectangular court and a star, demonstrating different methods to find the perimeter. It concludes with practical applications of perimeter in daily life, emphasizing its relevance and utility.

What is the shape of the block discussed in the introduction?

• Triangle

• Rectangle

• Square

• Circle

What is the perimeter of a rectangle with a length of 16 meters and a width of 8 meters?

• 56 meters

• 24 meters

• 48 meters

• 32 meters

Which of the following is a correct method to calculate the perimeter of a rectangle?

• Divide the length by the width

• Add all the sides together

• Multiply the length by the width

• Subtract the width from the length

How many sides does the star-shaped polygon have?

• 10

• 8

• 5

• 12

If each side of the star is 8 cm, what is the perimeter of the star?

• 88 cm

• 80 cm

• 72 cm

• 64 cm

What is the unit of measurement for perimeter?

• Meters

• Cubic meters

• Square meters

• Liters

What should you do if you want to calculate the perimeter of a polygon?

• Subtract all sides

• Add all sides

• Divide all sides

• Multiply all sides

Why is it important to understand the concept of perimeter?

• To find the volume of a shape

• To measure the height of a shape

• To understand the length around a shape

• To calculate the area of a shape

What is the difference between perimeter and area?

• Perimeter is the sum of all sides, area is the space inside

• Perimeter is the space inside, area is the sum of all sides

• Perimeter is always larger than area

• Perimeter is measured in square units, area in linear units

How can you apply the concept of perimeter in real life?

• By calculating the distance around a park
