As we learnt in

Definition of work by constant force -

w = underset{F}{ ightarrow}.underset{S}{ ightarrow}

- wherein

The scalar product of the force vector (underset{F}{ ightarrow}) and the displacement vector (underset{S}{ ightarrow})

 Work done = Area under (f.d) graph = Area of rectangle ABCD +  Area of triangle DCE

= 2\times (7-3)+\frac{1}{2}\times 2(12-7)= 8+5 = 13 J
