The answer is B, kilometers.
—Evidence—
•] it is assumed that there are 6 stadia in a kilometer (km), meaning that Eratosthenes found the Earth's circumference to be about 42,000 km
Answer is 279
Step-by-step explanation:
Lets do the following:
How many 1/9 are there in 1? Easy! 9. We can corroborate this by summing 1/9 nine times of multiplying 1/9 nine times. In both cases the result is 9.
Then, how many 1 are there in 31? Easier!! 31. Is we sum the number 1 thirty one times, the result is 31.
Now let join both results:
If each 1 has nine 1/9, and there are thirty one 1s in 31, then in 31 we have 31*9=279 1/9s. This is:
31*1 = 31 * 9 (1/9) = 279 * (1/9)
The third side is = 4
This is a perfect square. Also, using the Pythagorean theorem you can find the third side
3squared + xsquared = 5 squared
9 + xsquared = 25
xsquared = 16
sqrt of 16 = 4
