⟩ A man walks 3km east then 5km north then 8km east. Now how far is he from the starting point
if u draw a rectangle of length of total(3+8) km and breadth 5km and draw a diagonal from the starting to ending point, by Pythagaros Theorem, square(hyp)=square(the both sides)
Therefore, 25+121=sqrt(answer)
it comes to be 12.083km
