Understanding the Area of a Trapezoid

The video tutorial explains how to find the area of a trapezoid on a coordinate plane. It begins with an introduction to the trapezoid area formula, which involves averaging the lengths of the bases and multiplying by the height. The tutorial then demonstrates how to calculate the lengths of the bases and the height using the distance formula, which is an application of the Pythagorean theorem. Finally, it shows how to substitute these values into the formula to find the area of the trapezoid.

What is the formula for the area of a trapezoid?

• Base 1 + Base 2 + Height

• Base 1 * Base 2 * Height

• Average of the bases times the height

• Base 1 - Base 2 + Height

Which segment is identified as Base 1 in the trapezoid?

• Segment OW

• Segment WL

• Segment CL

• Segment CN
