Area Of Trapezoids: The formula to calculate the area of a trapezoid

The video tutorial explains how to calculate the area of a trapezoid by dividing it into two triangles. It starts by reviewing the formula for the area of a triangle, which is 1/2 base times height. The tutorial then applies this formula to two triangles formed by cutting the trapezoid along its diagonal. By adding the areas of these triangles, the area of the trapezoid is determined. The process is simplified by factoring out common terms, resulting in the formula 1/2 * H * (B1 + B2) for the trapezoid's area. The tutorial concludes by emphasizing the importance of understanding the relationship between the bases and height in these calculations.

What is the formula for calculating the area of a triangle?

• 1/3 * base * height

• base * height

• 1/2 * base * height

• base + height

How do the areas of the two triangles differ in the trapezoid?

• They have different heights

• They have different colors

• They have different angles

• They have different bases

What is the formula for the area of a trapezoid derived in the video?

• B1 * B2 * height

• B1 + B2 + height

• 1/2 * (B1 + B2) * height

• 1/3 * (B1 + B2) * height

What common terms are factored out to simplify the trapezoid area formula?

• Height and base

• B1 and B2

• 1/2 and height

• Base and height

What should you remember about the bases and height in the trapezoid area formula?

• Height is not important

• Height is the average of B1 and B2

• B1 and B2 are the same

• B1 and B2 are different bases
