ANSWER IS 112
HOW TO DO PLS TELL​

Answer 1

Answer:

The girl runs round the playground twice means he covered the perimeter of that playground two times.

so, Perimeter of rectangular ground =2(l+b)

=2(42+38)=172m

But she covers it twice so she covers

Perimeter of ground ×2 = 172×2=344m

Answer 2

Answer:

length of the field=42m

breadth of the field=38m

perimeter of the field=2(42+38)

it's given that the girl runs 2 round

means -160*2=320 m
