Find the area of the Compound shape

The answer is 333 cm^2

I just need the steps.

333cm^2

Step-by-step explanation:

Divide the compound shape into the two separate parts, the rectangle and the triangle.

The rectangle measuring 18cm by 14cm, getting the area, use the formula length*width. This is 18*14= 252cm^2.

Then the triangle has the height, 9cm and base 18cm, finding the area use the formula, 1/2*base*height.

1/2*9*18= 81cm^2.

Add the two, 252+81= 333cm^2.
