Understanding the Area of a Trapezoid

The video tutorial explains how to find the area of a trapezoid by averaging the lengths of its two parallel bases and multiplying by the height. It provides a step-by-step calculation using specific base and height values, resulting in an area of 52 square centimeters. The tutorial also offers an intuitive explanation of why the formula works by comparing the trapezoid's area to the areas of rectangles formed by the bases and height.

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

• Average of the bases times the height

• Difference of the bases times the height

• Sum of the bases times the height

• Base times height

How do you calculate the average of the bases in a trapezoid?

• Add the bases and multiply by two

• Subtract the smaller base from the larger base

• Add the bases and divide by two

• Multiply the bases and divide by two
