Hope it helps.

Answer 2

5 km distance will be covered by him to come back to his house.

Step-by-step explanation:

Suresh starting from his house, goes 4 km in the east, then he turns to his right and goes 3 km.

It forms a right angle with p = 3 km, b = 4 km

We have to find h which is the minimum distance will be covered by him.

By using pythagorean theorem,

$h = \sqrt{p^{2} + b^{2}}\\\\h =\sqrt{3^{2}+4^{2}}\\\\h = \sqrt{9+16}\\\\h = \sqrt{25}\\\\h = 5 \ km$

Hence, 5 km distance will be covered by him to come back to his house.
