#### Area under a v – t graph represents a physical quantity which has the unit(a) $m^2$(b) m(c) $m^3$(d) $ms^{-1}$

Ans. B

Sol.

Area under any x-y Graph will have unit as product of unit of x and unit of y.

That means area under the Graph of velocity and time will have unit equal to Product of unit of velocity (m/s) and unit of time (s).

That would be meter.

For the information, the area under the v-t graph gives displacement.

Hence, the correct option is option B
