Answer:
20 square meters
Step-by-step explanation:
To do this continue the line of the top of the rectangle so you split the figure into a triangle and a rectangle. The dimensions of the rectangle would be 8 by 2, so 8 * 2 = 16. Next, the dimensions of the triangle would be (4 - 2) by (8 - 4) = 2 by 4. The area would then be 2 * 4 = 8/2 = 4.
All you have to do now is add those two areas together, 16 + 4 = 20 square meters.
