Answer:
The answer is 74.
Step-by-step explanation:
To find the area, you have to divide the shape into rectangles. To solve, I divided it like the image above. (Sorry if the lines are squiggly I'm trying to do this fast)
So first, now that we've divided it into smaller rectangles, we find the area of the smaller ones. Remember, the area of a rectangle is length * height.
Since the two smaller rectangles are the same, we just need to find one and multiply it by 2.
So the area of the two smaller ones is 30. Now we need to find the big rectangle and add it together. We know that the length is 11, but we don't know the height. The height of the small rectangles was 5, so the height is 4 since 9 - 5 = 4. So to finish up, we do this:
So our final answer is 74.
