Dear Student!
1) Kindly go through the link given below to view the solution of the question which is converse of the question asked by you.
I am sure once you carefully go through the solution, you will be able to solve your query on your own. If still you face any difficulty then do get back to us.
2) Here is the answer to your query.
The given information can be represented using a figure as
Here, A and C are the position of the man at the starting point at ending point and AC is the distance between the starting and ending points.
Using Pythagoras theorem in ∆ABC
AC2 = AB2 + BC2
⇒ AC2 = (20 cm)2 + (15 m)2 = (400 + 225) m2 = 625 m2 = (25 m)2
⇒ AC = 25 m
Thus, the required distance is 25 m
