Plse me plse pic included .. find the area of the following shape. you must show all work to receive credit.

Excuse my crummy writing. Anyways, all I did was section this shape into smaller shapes that I can work with (triangles and rectangles). I'll link the picture below. The area of the blue triangle is 4.5. The area of the purple triangle is 13.5. The area of the red triangle is 3. The area of the orange and the black rectangles (they're identical) is 18. Add these areas up to get the total. 4.5 + 13.5 + 3 + 18 + 18 = a grand total of 57 units

Hope this helps :)

answer: the common difference is -0.10

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
