Rectangle ABCD consists of two equal triangles. The area of the rectangle ABCD = AB * AD, and the area of any of the triangles is half the area of the rectangle. Let’s say AB = CD = 5 centimeters, and AD = CB = 2 centimeters. Then the area of the rectangle ABCD = 5 * 2 = 10 square centimeters. The area of the triangles ABC = ADC = 10: 2 = 5 square centimeters.
