Can you help me on this question please

20 units²

Step-by-step explanation:

We can split the polygon into two triangles along the x-axis.

To work out the area of the top triangle, we can do 1/2 × b × h → a = 1/2 × 4 × 4 = 8 units²

To work out the area of the bottom triangle, we can do 1/2 × b × h → a = 1/2 × 4 × 6 = 12 units²

8 + 12 = 20 units²

Hope this helps!
