(D) 18 km
Answer nicely​

Answer 1

Answer:

15 km

step by step explanation

if he walks 3 km to east and turns to his left means north and walks 3 times means 9 km and then again he turns to his left means west 5 times means 15km. So, we have to solve by Pythagoras theorem.

base=15-3=12

length=9km

hypotenuse=?

12²+9²=144+81=225

√225=15

so, our answer is 15 km
