What math are you in because I can ask my friends for help
For example, in the number 14,509, fourteen thousand five hundred and nine, 1 is in the ten thousands place, and zero is in the tens place.
1 4, 5 0 9
ten thousand^ ten^
11 836/1000. Simplified: 11 209/250.
I hope this helps! :)

8 is the simplest form from that I could find.
CB = DA = √3*3+1*1 = √10
CD = BA = √2*2+1*1 = √5
Sum is 2√10 + 2√5 ≈ 10.8. So answer A.
