Learn to find the area of a trapezoid

The video tutorial explains how to find the area of a trapezoid. It begins with a definition of a trapezoid, highlighting its characteristics such as having four sides and at least one pair of parallel lines. The tutorial then introduces the formula for calculating the area: 1/2 * (base1 + base2) * height. It guides viewers on identifying the bases and determining the height, using a practical example with specific measurements. The video concludes with a step-by-step calculation, resulting in an area of 119 square feet, emphasizing the importance of using consistent units.

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

• 1/2 * (base1 + base2) * height

• base1 + base2 + height

• base1 * base2 * height

• 1/3 * (base1 + base2) * height

Which of the following best describes the bases of a trapezoid?

• The shortest sides of the trapezoid

• The non-parallel sides of the trapezoid

• The parallel sides of the trapezoid

• The longest sides of the trapezoid

How is the height of a trapezoid determined?

• The distance between the two bases

• The sum of the side lengths

• The diagonal length

• The length of the longest side

What is the area of a trapezoid with bases 23.9 feet and 10.1 feet, and a height of 7 feet?

• 140 square feet

• 130 square feet

• 150 square feet

• 119 square feet

Why is the area of a trapezoid expressed in square units?

• Because it represents a volume

• Because it represents a length

• Because it represents a two-dimensional space

• Because it represents a weight
