Look at the picture below // 99 points //

I'm pretty sure it's D, hope this helps, have an amazing day :)

Lets get started :)

We can divide the large polygon into 3 smaller known polygons 
1 square and 2 rectangles

The dimensions of the square will be:
width: 3 units
length: 3 units 

The dimensions of the 1st rectangle will be:
width: 4 units
length: 7 + 13 = 20 units

The dimensions of the 2nd rectangle will be:
width: 5 units
length: 13 units

The area formula of square is (side)²
A = (6)² = 36 units²

The area formula of a rectangle is (length x width)
A (1st) = 4 x 20
           = 80 units² 
A(2nd) = 5 x 13
            = 65 units²

Now, we add all the areas to get the final area
Area total = 36 + 80 + 65
                 = 181 unit²

Your final answer will be option D

Where's the rest of the
