Understanding the Area of a Right Trapezoid

What are the two parallel sides of a trapezoid called?

• Length and Width

• Base and Height

• Height and Width

• B sub 1 and B sub 2

How should you measure the length of a line on a graph?

• By treating it as a number line

• By measuring the area

• By counting the squares inside the shape

• By using square units

What is the length of B sub 1 in the example?

• 10

• 8

• 6

• 4

What is the formula used to calculate the area of a trapezoid?

• B1 + B2 + Height

• B1 * B2 * Height

• B1 * B2 / Height

• (B1 + B2) / 2 * Height

What is the area of the trapezoid in the example?

• 36 square units

• 24 square units

• 12 square units

• 48 square units

Why do we divide the sum of the bases by 2 in the area formula?

• To calculate the height

• To find the perimeter

• To find the average length of the bases

• To simplify the equation

What does finding the average of the two bases help us visualize?

• A triangle

• A circle

• A square

• A rectangle

How does transforming a trapezoid into a rectangle help in understanding its area?

• It highlights the height

• It demonstrates symmetry

• It simplifies the calculation

• It shows the perimeter

What happens to the bases when visualizing the trapezoid as a rectangle?

• They halve in length

• They become equal

• They disappear

• They double in length

What is the final shape used to understand the area of a trapezoid?

• Triangle

• Rectangle

• Circle

• Square
