I got 7.1 x 10^(-11) but it's been a few years so I could've done it wrong
If you rotate about the circumcentre of a regular polygon 72° it will overlap with the original image.
Ok, so you automatically know that you are subtracting 6 from 10 to get 4. So, in order to figure out how it is 1/3 of that number, it is going to be multiplied by 3, getting 18. So, the number would be 18.
Answer:
272.5 m²
Step-by-step explanation:
1/2x4x9=18
(9+18)/2=13.5. 13.5x11=148.5
(18+14)/2=16. 16x7=112
12+148.5+112= 272.5
-11/12 +5/12 = - 6/12= - 1/2
