Calculating Area and Perimeter of Trapezoids

This video tutorial explains how to calculate the perimeter and area of a right trapezoid. It begins with defining the perimeter as the total distance around the trapezoid and demonstrates the calculation by summing the lengths of its sides. The tutorial then moves on to calculating the area, using the formula for the area of a trapezoid, which involves the sum of the bases and the height. The video provides a clear, step-by-step guide to these calculations, ensuring a comprehensive understanding of the concepts.

What is the perimeter of a polygon?

• The distance around the outside of the polygon

• The length of the longest side of the polygon

• The area inside the polygon

• The sum of the angles of the polygon

How do you calculate the perimeter of a right trapezoid?

• By multiplying the lengths of its bases

• By adding the lengths of all its sides

• By subtracting the height from the base

• By dividing the sum of the bases by two

What is the perimeter of the right trapezoid in the example?

• 26.4 feet

• 25.4 feet

• 27.4 feet

• 24.4 feet

What is the formula for the area of a trapezoid?

• Base minus height

• Base plus height

• One-half times the sum of the bases times the height

• Base times height

In the formula for the area of a trapezoid, what do the 'bases' refer to?

• The two non-parallel sides

• The two parallel sides

• The height and the base

• The longest and shortest sides

What is the height of the right trapezoid in the example?

• 8 feet

• 7 feet

• 6 feet

• 5 feet

What is the area of the right trapezoid in the example?

• 41 square feet

• 43 square feet

• 42 square feet

• 40 square feet

Why is the area of the trapezoid expressed in square feet?

• Because it is a three-dimensional measurement

• Because it is a one-dimensional measurement

• Because it is a four-dimensional measurement

• Because it is a two-dimensional measurement

What operation is performed first when calculating the area of the trapezoid?

• Multiplication

• Division

• Addition

• Subtraction

What is the final step in calculating the area of the trapezoid?

• Dividing by two

• Multiplying by one-half

• Multiplying the result by the height

• Adding the bases
