Understanding Perimeter Calculation

The video tutorial explains how to calculate the perimeter of a triangle by adding the lengths of its sides. It demonstrates the process of combining like terms in an algebraic expression to simplify the calculation. The tutorial uses visual aids to highlight like terms and guides the viewer through the steps to arrive at the final perimeter value.

What is the perimeter of a shape?

• The height of the shape

• The volume of the shape

• The distance around the outside of the shape

• The area inside the shape

How do you calculate the perimeter of a triangle?

• Multiply all sides together

• Add all sides together

• Subtract the smallest side from the largest

• Divide the longest side by the shortest

What is the first step in finding the perimeter of a triangle?

• Identify the longest side

• Add the lengths of all sides

• Multiply the base by the height

• Subtract the base from the height

What does it mean to combine like terms?

• Adding different variables together

• Multiplying different variables

• Grouping and adding similar variables

• Subtracting similar variables

How do you identify like terms in an expression?

• By identifying terms with different coefficients

• By checking for terms with different variables

• By finding terms with the same variables

• By looking for terms with the same coefficients

What is the result of combining 5x and 2x?

• 10x

• 3x

• 7x

• 2x

What is the final expression for the perimeter after combining like terms?

• 6x + 5y

• 7x + 4y

• 8x + 2y

• 5x + 3y
