The area of the rectangle plus the area of the triangle under the line

Explanation:

In a vleocity Vs time graph, the change in position of an object is given by

x_{1}-x_{2} = / int/limits^T_t {v} /, dt

where the integral can be taken from the graph as

/int/limits^T_t {v} /, dt=area between velocity curve and time axis from t to T
