The area of the quadrilateral can be calculated by finding the area of the two triangles formed and then adding them together.
Area of triangle 1 = 1/2 * base * height
Area of triangle 1 = 1/2 * 10 * 8
Area of triangle 1 = 40 cm^2
Area of triangle 2 = 1/2 * base * height
Area of triangle 2 = 1/2 * 10 * 8
Area of triangle 2 = 40 cm^2
Adding the areas of the two triangles together:
Total area = 40 cm^2 + 40 cm^2
Total area = 80 cm^2
Therefore, the area of the quadrilateral is 80 cm^2.
