Answer: 92.0 mm squared
Step-by-step explanation:
To help solve for the total area we can split the shape into two rectangles then find the area of those two rectangles and add them together.
The first rectangle at the top is a 4 by 3 mm.
4*3 = 12 mm squared
The second rectangle on the bottom is a 10 by 8 mm.
10*8 = 80 mm squared
The total will now come from those areas added together.
80 + 12 = 92 mm squared
