1. The perimeter is 20. How I got that is to add all of them together- 9+3+3+3+2=20. The area is the area is 15. How I got that was I did the little square with 3 and 2 first. 3 times 2 = 6, then I did the 3 and 3 which = 9 and added those together 9+6=15
2. The perimeter is 15. How I got that is I add them all together. 6+3+2+2+2=15. The area is 10. I did 3 times 2 = 6, 2 times 2 = 4, 6+4=10

Answer: 9 × 10^11
Step-by-step explanation:
An index number is simply referred to a number that is being raised to a particular power or index which tells us the amount of times the number will be multiplied by itself. An example is 10³ which means we have to multiply 10 thrice and this will be:
= 10 × 10 × 10
= 1000
For 866,214,000,000, this can be expressed as:
= 8.66214 × 10^11
We should note that 8.66214 can be changed to the nearest whole number which will be approximated to 9.
Therefore, the answer will be:
= 9 × 10^11
