This math topic focuses on calculating the area of a trapezoid. It teaches students to find the area by multiplying the height of the trapezoid by the average length of the two parallel sides. The topic covers various problems where students apply this formula to different trapezoids, using given measurements. Students are provided with diagrams of trapezoids alongside measurement details and are required to choose the correct area calculation from multiple options. This topic is part of a broader unit on the area and perimeter of basic shapes.
