The area of a trapezoid can be calculated using the formula: Area = 1/2 * (sum of the lengths of parallel sides) * height.
In this case, the sum of the lengths of the parallel sides is 10 inches (left side) + 16 inches (right side) = 26 inches. The height (which is the length of the top slanting side) is 7 inches.
Plugging these values into the formula: Area = 1/2 * 26 inches * 7 inches = 91 square inches.
Therefore, the area of the quadrilateral is 91 in.².
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.
