Never forget to consider the -ive values



l * b < = 20

When we plot the values on the graph, we can get breadth as 4, but now the length can be from -5 < = x < = 5

x != 0

Answer D

I ignored the -ve values?

Hi Chei

That is correct, the distance will always be a positive value even if i take length as y = -1

I realized it later after marking the question as C :-D
