Question

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

Answer 1

Answer:

38 m

Step-by-step explanation:

$distance \: covered = 2(l + b) + \sqrt{ {l}^{2} + {b}^{2} } \\ \\ = 2(8 + 6) + \sqrt{ {8}^{2} + {6}^{2} } \\ \\ = 28 + 10 \\ \\ = 38 \: m.$
