2) Find the area of the trapezoid.

Solution:

• The area of a trapezoid is calculated using the formula: Area = (1/2) * (sum of parallel sides) * height.
• In this trapezoid, the lengths of the parallel sides are 9 and 18, and the height is 4.
• Area = (1/2) * (9 + 18) * 4 = (1/2) * 27 * 4 = 27 * 2 = 54.

Answer: 54
