This math topic focuses on determining the area of trapezoids based on forming equivalent rectangles. Students are required to apply the concept that the area of a trapezoid can be represented as the area of a rectangle formed by using the average of the bases of the trapezoid and its height. This involves solving for the areas using various given dimensions. Each question provides different measurements and asks the students to select the correct area equation among multiple choices. This exercise helps deepen the understanding of area calculation while reinforcing algebraic manipulation and geometry concepts.
