Use the image to answer the question.
An illustration shows a trapezoid with top side as 4 centimeters, and the left as the longest side of 9 centimeters. The opposite parallel side on the right is 6 centimeters. A diagonal bottom side is 5 centimeters. The top side is perpendicular to the left and right sides as denoted by right two angle symbols. A perpendicular dotted line from the bottom right vertex to the left side is drawn. The dotted line makes one right angle symbol with right side and two right angle symbols with the left side. It forms a right triangle at the bottom of the trapezoid, with the 5 centimeter side as the hypotenuse.
Find the area of the quadrilateral.

The area of the trapezoid can be calculated by adding the areas of the two triangles formed within the trapezoid. The area of a triangle is given by the formula: (base x height) / 2.
The area of the top triangle is: (4 cm x 4 cm) / 2 = 8 cm2
The area of the bottom triangle is: (6 cm x 5 cm) / 2 = 15 cm2
Therefore, the total area of the trapezoid is: 8 cm2 + 15 cm2 = 23 cm2
The correct response is not among the options given. The closest option is 24 cm2, which is the correct answer when rounded to the nearest whole number.
