Will give brainliest to the best (& first) answer~!

(05.03)an irregular polygon is shown below:

the area of the irregular polygon is square units.

image of irregular polygon with length of 8 units and height of 3 units labeled on left side. top side length of 4 units, the side adjacent to it on the right is 1 units.

Well first you have to cut the polygon into 2 pieces. I would cut from the 1 unit line down. Multiply 3 x 4, which equals 12. The other piece is 8 square units because the other side is 3 units. So the 2nd piece side is 2 units. The bottom is 4 units long. Multiply 2 x 4=8. 12+8=20. Answer is 20 squared units. :)

fine
