Calculating Position from Acc. Time Graph

[bigzee20]

How can i figure out the instantaneous position of an object using an acceleration time graph. Iam also given initial velocity and initial position? Thanks

The area under the curve between two time points of the a-t graph is the total change in velocity between those two time points.

The area under the curve between two time points of the v-t graph is the total change in displacement between those two time points.

Is there an specific formula for it?
