The length and breadth of a room are 8 m and 6 m respectively. A cat runs along all the four walls and finally along a diagonal order to catch a rat. How much total distance is covered by the cat?

38 m

If the length and breadth of the room is 6 and 8, then with the help of Pythagoras theorem, its diagonal comes out to be 10. Thus, the total distance covered by the cat, according to the question will be:

Length + Breadth + length + breadth + diagonal = Total distance covered by the cat in order to catch the rat

8 + 6 + 8 + 6 + 10 = 38 m
