How do we measure magnitude of displacement from the speed time graph.

I understand that if the velocity is constant (acceleration=00) throughout the course of motion (where graph shows a rectangle) then it would simply be like playing with equation:
(1). velocity=displacement/time
(2). displacement=velocity ×× time =area of rectangle =Velocity-axis ×× time-axis,
putting the value of velocity and time, then getting out the displacement.
But what if the acceleration is constant instead of 00 (where graph shows a triangle) ? I know it would be 1212 velocity ×× time, but how we can put a value of velocity in (1) displacement=velocity ×× time When velocity is changing all time due to uniformly accelerated motion?
