Answer 1

The question is pretty easier if you think carefully and you can definitely solve it at once I've also attached the image of the diagram that I have drawn in context to the question. First of all he started walking street 20 m from his office and then took a right turn and walked for 10 M again he took a left on and then again walked for 10m and after that he turn right and walked for 20 M now at that moment he again turned right and walked for 70m. and the moment where he stopped from that place if we can find out the value of hypotenuse AC can see in the figure attached then the base will be of 30 cm or 30 units you can get 30 by adding 20 + 10 and the perpendicular will be 40 units now the hypotenuse distance will be Root over 40 square + 30 square which will give you root over 2500 and finally you can get 50.
