Answer: 297 square cm</h3>
=============================================
Work Shown:
Break up the figure as shown in the diagram below.
A rectangle and trapezoid form
-------------
Area of rectangle = base*height = 9*15 = 135 cm^2
Area of trapezoid = (1/2)*(b1+b2)*h = (1/2)*(18+9)*12 = 162 cm^2
total area = (area of rectangle)+(area of trapezoid)
total area = (135) + (162)
total area = 297 square cm
