 Hi in this question It's given that Or it is asking about area under VT graph represents a physical quantity which has the unit So basically we have to find out what does the area area Area under a VT graph represents. So what is what is being asked? It's asking about area Under what under a VT? Graph so what does area under a VT graph represent, you know that area under a VT graph represents represents displacement Displacement so if we have to find out the displacement of A body whose VT graph is given we just need to find out the area of The VT graph what do we mean by finding out the area of the VT graph? Let's say this is V and this is T and this is how the VT graph looked like So basically if we if you want one to find out the displacement displacement Covered from let's say at time T equals to zero so time T equals to T. Let's say this is time T equals to T T equals to T. So what do we need to do is we just need to find out this area We need to find out So area between T equals to zero to T equals to T Okay, so How do we find out the area if this is a regular shape? That is if it is a line then it is easier to find out how is we can find out that area of trapezium a D C D Okay, and we know that area of trapezium a B C D area in this case will be half into Some of parallel sides some of parallel sides multiplied by distance between the parallel side distance between the Parallel side Okay, so but clearly we know that area under VT graph represents displacement What's the unit of displacement? This placement is measuring meters. So hence the unit will be meters, right? So it's in this case Option B is correct
