Geometric Properties to Find the Perimeter of Plane Figures (Part 1)

The video tutorial explains how to calculate the perimeter of a plane figure, specifically a quadrilateral, by adding the lengths of its sides. It demonstrates simplifying numbers for easier addition and combines these results to find the final perimeter, which is 76 centimeters.

What is the perimeter of a shape?

• The width of the shape

• The volume of the shape

• The total length of its sides

• The area of the shape

How do you find the perimeter of a quadrilateral?

• Add the lengths of its sides

• Subtract the lengths of its sides

• Divide the lengths of its sides

• Multiply the lengths of its sides

What is the first step in simplifying the addition of side lengths?

• Break down numbers into tens and ones

• Divide the numbers

• Multiply the numbers

• Subtract the numbers

What is the sum of two 20's and two 10's?

• 70

• 60

• 50

• 40

What is the final perimeter of the quadrilateral?

• 72 centimeters

• 74 centimeters

• 78 centimeters

• 76 centimeters
