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?

It looks like your question about the room's dimensions got cut off. You mentioned the length is 8 meters, but the breadth is missing. Could you please provide the breadth of the room or complete your question? That way, I can help you with calculations like area, perimeter, or anything else you need.
