Answer is D

Each statement alone is enough to answer
You need to observe carefully to answer this question
consider the length n breadth to be "l" , "b"

1) the total length is 3l+3b
we can find value of l+b and the perimeter of big rectangle too
2)the total length is 3l+3b
we can find value of l+b and the perimeter of big rectangle too
