What is the area of S-t graph

Area under DT graph

Important: The area between a velocity-time graph and the `time' axis gives the displacement of the object. The slope is the same all the way from A to C, so the cyclist's velocity is constant over the entire displacement he travels. In figure 5.1 are examples of the displacement-time graphs you will encounter.

the second one and the forth one are in the purple because they are opinions and the rest are in the yellow

explanation:

i think the answer is a and b

i wish you luck
