Understanding Perimeter

The video tutorial explains the concept of perimeter using a garden fence analogy. It demonstrates how to calculate the perimeter of rectangles by counting steps around them and introduces the formula for perimeter as 2 times the length plus 2 times the width. The tutorial uses variables to simplify the formula and provides examples of applying the formula to find the perimeter of given rectangles.

What is the main concept introduced at the beginning of the video?

• Volume measurement

• Perimeter calculation

• Area calculation

• Surface area

What is the perimeter of the orange rectangle?

• 22

• 20

• 18

• 16

Which pattern is observed in the perimeter calculation of the orange rectangle?

• The numbers appear two times

• The numbers appear three times

• The numbers appear four times

• The numbers appear once

What is the formula for calculating the perimeter of a rectangle?

• P = L + W

• P = 2L + 2W

• P = L x W

• P = 2(L + W)

• Area

• Width

• Length

• Perimeter
