Answer: 398

Step-by-step explanation: First I find the area of the biggest triangle 20x20x1/2=200.

Then I find the area of the rectangle by cutting off the triangle at the end 6x30=180.

After that I find the area of the small triangle 6x6x1/2=18.

Finally, I add all the area up and 18+180+200= 398

Hope this helps :)

Answer:

398

Step-by-step explanation:

To find the answer all you have to do is to find the area of this shape. Area= Base x Height.

First step: Is to subtract 26-6. That will give you 20. 

Second Step:  That will give you 200 because 20 × 20= 400 / 2 = 200.

Third Step: Calculate the triangles by cutting them. . That will give you 18 because 6 × 6= 36, and 36 / 2 = 18.

Fourth Step: Multiply 30x6. 30x6=180

Final Step:Add 200+180+18. That will give you 398.
