Answer: 330 (unit of measure) ²
Explanation:
Ok so first you got to "unfold" the shape, and find the area of each part in the unfolded version. Then you add up the areas.
30 + 30 (The areas of the right triangles; formula for area: 1/2 base x height) + 108 + 45 + 117 (The rectangles, which are different, by the way; formula for area: base x height, or length x width). Adding that, you should get 330.
So your answer should be 330 (unit of measure) ²
Hope this helped, lol, I am in middle school and we had this on our finals.
