Step-by-step explanation:
Well we can divide the given polygon into smaller triangles.
The triangle on the upper right corner has a base of 4 units and a height of 3 units.
So we use the following formula,
4*3 = 12
12 / 2 = 6 units^2
Now we can do the bottom triangle.
It has a base of 4 units and a height of 1 unit.
So 4*1 = 4
4 / 2 = 2 units^2
Now for the top left triangle.
It has a base of 4 units and a height of 2 units.
So 4*2 = 8
8 / 2 = 4 units^2
Now all we have is the middle part.
Its a triangle with a base of 4 units and a height of 2 units.
So 4*2 = 8
8 / 2 = 4 units^2
6 + 2 + 4 + 4 = 16 units^2
<em>Thus,</em>
<em>after adding everything up the total area of the polygon is 16 units^2.</em>
<em>Hope this helps :)</em>
