Answer:
C. 54cm²
Explanation:
Split the figure into 2. A=LW. the top shape is easy, 8x5 = 40
As for the bottom one, we need to figure out the height. The whole left side is 12cm, and the part in the top shape is 5cm since it is across from the labeled side, and is a rectangle. 12-5= 7, the height of the smaller shape.
From there, we use LW to figure that out. 7x2 = 14
Now we know the area of both shapes, so we must add them together. Think of it as finding the area of each shape seperately, which is what we did. 40 + 14 = 54 and don't forget the label!
