Question Analysis

The main focus is on applying the formula for the area of a trapezoid to calculate the area using the given lengths of the bases and the height.

 

Key Concept Explanation

The area  of a trapezoid is calculated by the formula , where  and  are the lengths of the two bases and  is the height. This formula is based on the idea of combining two identical trapezoids to form a parallelogram, and then taking half of the parallelogram's area.
