Don't really understand this

Answer 1

Answer:

24 units²

Step-by-step explanation:

In this polygon to find the area you have to split it into 2 shapes. In this case, splitting it into a quadrilateral and a triangle makes the most sense. Let's find the area of the rectangle first. To do that, count the amount of units on the base and height and multiply them. In this case, that would be 4×5 so 20u². Now we have to find the triangle area. We see that the triangle has a right triangle so the formula would be base*height/2. In the picture, we can see that the base is 2 and the height is 4 so we would do 4×2 (8) divided by 2 to get 4u². Now add the rectangle and triangle height to get an answer of 24u² for the area.
