How to find the area of a trapezoid using the formula

The video tutorial discusses class dynamics and the importance of focus before introducing the formula for calculating the area of a trapezoid. It explains how to identify the bases and height of a trapezoid and demonstrates the calculation process using the formula. The lesson concludes with a brief wrap-up.

What is the formula for finding the area of a trapezoid?

• Area = height / (base1 + base2)

• Area = base1 + base2

• Area = height * (base1 + base2)

• Area = 1/2 * height * (base1 + base2)

How do you determine which sides are the bases of a trapezoid?

• The shortest sides are the bases.

• The parallel sides are the bases.

• The sides that are not parallel are the bases.

• The longest sides are the bases.

What is the height of a trapezoid?

• The sum of the two bases.

• The average of the two bases.

• The length of the longest side.

• The distance between the two bases.

If base1 is 12, base2 is 22, and the height is 16, what is the area of the trapezoid?

• Area = 272

• Area = 270

• Area = 280

• Area = 260

Why is it important to perform operations inside parentheses first when calculating the area?

• To simplify the calculation.

• To avoid using the wrong formula.

• To ensure the correct order of operations is followed.

• To make the calculation faster.
