Perimeter and Area of Triangles and Rectangles

This video tutorial from MooMoo Math and Science explains how to calculate the perimeter and area of triangles, rectangles, and squares. It provides step-by-step examples for each shape, demonstrating how to add sides for perimeter and multiply dimensions for area. The video also covers combining like terms in algebraic expressions to simplify calculations.

What is the perimeter of a shape?

• The distance around the outside of the shape

• The space inside the shape

• The length of the longest side

• The sum of the angles

How do you calculate the perimeter of a triangle?

• Divide the sum of the sides by two

• Subtract the smallest side from the largest

• Add all the sides together

• Multiply the base by the height

What is the result of combining like terms in the expression 3y + 5x + 2x + y?

• 6y + 5x

• 3y + 5x

• 4y + 7x

• 5y + 7x

What should you do if a side length is missing when calculating the perimeter of a rectangle?

• Assume it is zero

• Use the length of the opposite side

• Guess the length

• Ignore it

If a rectangle has sides 11D and 5, what is its perimeter?

• 32D

• 44D

• 11D + 5

• 22D + 10

How is the area of a rectangle calculated?

• By subtracting the width from the length

• By dividing the length by the width

• By multiplying the length by the width

• By adding all the sides

What is the area of a rectangle with sides 11D and 5?

• 55D

• 16D

• 22D

• 11D + 5

What is the formula for the perimeter of a square?

• Side length plus 4

• Side length divided by 4

• Side length squared

• 4 times the side length

How can you simplify the process of finding the perimeter of a square?

• By measuring each side individually

• By guessing the side length

• By using a formula

• By adding the area to the perimeter

What is the perimeter of a square with side length 8V?

• 8V

• 32V

• 64V

• 16V
