Use the image to answer the question.
An illustration shows a trapezoid with shorter base of length 36 and the opposite longer side of length 48. The legs on the left and right sides are of length 21. The perpendicular height from the bottom left vertex to the longer side is 18. The length between the top left vertex of the longer side and the point where the height meets the longer side is labeled 6. The height is shown in a dashed line.

To find the area of the trapezoid-shaped table top, we can create a rectangle by moving the triangle piece (6 x 18) to the right side of the trapezoid to form a rectangle.
The dimensions of the rectangle are 30 x 18. Therefore, the area of the rectangle (and thus the trapezoid-shaped tabletop) is 30 x 18 = 540 square inches.
Therefore, the area of the trapezoid-shaped tabletop is 540 square inches.
