This document discusses formulas for finding the areas of trapezoids, kites, and rhombuses. It states that the area of a trapezoid is one half the height multiplied by the sum of the bases. The area of a kite is one half the product of the lengths of its diagonals. Similarly, the area of a rhombus is equal to one half the product of the lengths of its diagonals. It provides examples of using these formulas to calculate areas.
