Answer 1

Answer:

When there are 5 rounds, its perimeter is also multiplied by 5 to measure distance.

Perimeter = 2(l+b)

if it is 5 times, then its perimeter is multiplied by 5 which becomes 15(l+b)

sum of l and b is multiplied by 15

So answer is (c) 15

Answer 2

Answer:

10

Step-by-step explanation:

Distance covered in one round = 2l + 2b

So, distance covered in 5 rounds = 5*2l + 5*2b = 10l + 10b

                                                          => 10(l+b)
