Question

Photo above! How do I find the area of this? I'm more concerned about how to find the answer than the actual answer itself. I just need to know how to find the area

Answer 1

Well, this is how I do it. Multiply 4 and 10 and get the area of the whole thing. Answer is 40. Then, multiply 3 and 5. (I got 5 from subtracting 2 and 3 from 10). This gives me the area of the missing piece. Answer is 15. Lastly, I subracted. 40 - 15. Gave me 35. My final answer I got is 35. I hope my answer is correct! I hope this helped!

Answer 2

(2·4)+(1·5)+(3·4)=25
