Understanding Trapezoid Properties and Area

The video tutorial explains how to calculate the area of a trapezoid. It begins by defining a trapezoid as a quadrilateral with one pair of parallel sides and introduces the formula for its area: one-half times the sum of the bases times the height. The tutorial then applies this formula to a trapezoid with bases of 15 inches and 25 inches and a height of 5 inches. By following the order of operations, the calculation is simplified to find the area as 100 square inches.

What is a defining characteristic of a trapezoid?

• It has four equal sides.

• It has one pair of parallel sides.

• It has two pairs of parallel sides.

• It has no parallel sides.

Which of the following is the correct formula for the area of a trapezoid?

• Area = base * height

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

• Area = 1/2 * base * height

• Area = base1 + base2 + height

In the given trapezoid, what are the lengths of the bases?

• 15 inches and 25 inches

• 5 inches and 10 inches

• 10 inches and 20 inches

• 20 inches and 30 inches
