15% of the number 60 is 9
You would need to find the length of one wall then multiply it by 2 (since there are 2 walls) and then find the width and also multiply that by 2 and you would then add your to products (answers) to get the total length of your border
= 9 * 10^5 * 3 * 10^10
= 27 * 10^5 * 10^10
= 27 * 10^15
= 2.7 * 10^16 - The best selection appears to be the first option.
Good luck :)
Answer:7
Step-by-step explanation:distance between E and M forms a diagonal. Thus from the y axis we get a triangle. So using pythagoras theorem we have. EM^2= 5^2 +2^2. EM=\/(5+2)^2. EM=7
