Understanding the Area of a Trapezoid

The video tutorial explains how to find the area of a trapezoid on a coordinate plane. It introduces the formula for trapezoid area, identifies the bases and height, and demonstrates the calculation process. An alternative method using division is also explained, confirming the same result. The tutorial aims to provide a clear understanding of calculating trapezoid area using different approaches.

What is a trapezoid?

• A polygon with no parallel sides

• A quadrilateral with one pair of parallel sides

• A quadrilateral with two pairs of parallel sides

• A triangle with one pair of parallel sides

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

• 1/2 x B1 x B2 x H

• B1 + B2 + H

• 1/2 x (B1 + B2) x H

• B1 x B2 x H

How long is base 1 (B1) in the given trapezoid example?

• 3 units

• 4 units

• 7 units

• 10 units

What is the height of the trapezoid in the example?

• 10 units

• 4 units

• 3 units

• 7 units

What is the area of the trapezoid using the given dimensions?

• 24 square units

• 20 square units

• 10 square units

• 14 square units

How do you simplify 1/2 x 10 x 4?

• Multiply 10 by 4 and then divide by 2

• Divide 10 by 2 and then multiply by 4

• Add 10 and 4 and then multiply by 1/2

• Multiply 1/2 by 10 and then by 4

What is the alternative method to calculate the area of a trapezoid?

• Subtract the height from the sum of the bases

• Multiply by 2 instead of dividing by 2

• Divide by 2 instead of multiplying by 1/2

• Add the bases and multiply by the height
