Question

Sarita went to a park 20 m long and 10 m wide. She took one complete round of it. The distance covered by her is
30 m
60 m
20 m
10 m​

Answer 1

It's easy

One complete round of the park = perimeter of the park

Since the park is rectangular, its perimeter will be:

2(20+10) = 2(30) = 60 m

So, option 2 is right

Hope it helps :)

Answer 2

Answer:

First find perimeter

so the formula for rectangle's perimeter is 2(L+B)

=2(20+10)

=2×30

=60

Therefore She covered distance of 60 m
