Through B draw a line parallel to AD to meet DC at E. Clearly ABED is a parallelogram.

So BE=25, EC=DC-DE=17, BC=26

So by Heron's formula we can find the area of BEC and its value will be 204 sq.cm

So the altitude BF through B of BEC will have length 2*204/17=24 cm

So area of ABED is 24*60=1440

So the area of ABCD is 1440+204=1644
