Use the image to answer the question.
An illustration shows a trapezoid with parallel sides on the left and right. The left side is 10 inches and right side is 16 inches. The top slanting side is labeled 7 inches. Two perpendicular dotted lines of 6 inches each are drawn from the top and bottom left vertices to the right side.

The area of the quadrilateral can be found by dividing it into two triangles and a rectangle. The area of the quadrilateral is the sum of the areas of these shapes.
The area of the left triangle is (1/2)(6)(10) = 30 sq. in.
The area of the right triangle is (1/2)(6)(16) = 48 sq. in.
The area of the rectangle is (6)(7) = 42 sq. in.
Therefore, the total area is 30 + 48 + 42 = 120 sq. in.
Therefore, the area of the quadrilateral is 120 sq. in.
what is the answer
Apologies for the miscalculation in my previous responses.
The correct answer is: 78 in.2 or 78 in. squared.
This is calculated as the sum of the areas of the two triangles and the rectangle.
Area of left triangle = 1/2 * 6 * 10 = 30 sq. in.
Area of right triangle = 1/2 * 6 * 16 = 48 sq. in.
Area of rectangle = 6 * 7 = 42 sq. in.
Total area = 30 + 48 + 42 = 78 sq. in.
