Question

what does the area of distance vs time graph gives us?​

Answer 1

Area of distance time graphs give magnitude of no significant physical value.

Its slope gives velocity.

Answer 2

It is an unpleasant portmanteau called $\bold{absement}$.

Try getting your spellchecker to allow you to type that word. It is a combination of $\bold{abse}$nce and displace$\bold{ment}$ and is measured in length-time units (e.g. meter-seconds).
