The correct response is:
96 in.2
96 in. squared
To find the area of the quadrilateral, you can divide it into two triangles by using the bottom perpendicular line as the base. The area of each triangle is (1/2) * base * height. Adding the areas of the two triangles together gives the total area of the quadrilateral. Therefore, the area is (1/2 * 6 * 10) + (1/2 * 6 * 16) = 96 in^2.
