What is the area of the quadrilateral? 16in ,12in

To find the area of a quadrilateral, you can use the formula for the area of a trapezoid:

Area = h/2 * (b1 + b2)

where h is the height of the trapezoid and b1 and b2 are the lengths of the two parallel sides.

In this case, if the lengths of the two parallel sides are 16 inches and 12 inches, and the height is not given, we cannot calculate the area of the quadrilateral. We need to know either the height or the lengths of the diagonal sides to find the area.
