This is an easy question. Find co-ordinate values of A,B,C,D,E.

Then find Area of triangle ODC which is a right angled triangle. So, area(ODC)=(OD*OC)/2.

Then find Area of triangle DBE which is again a right angled triangle. So, area(DBE)=(BE*DE)/2.

Therefore Area of quadrilateral OCEB is area(DBE)-area(ODC).

 

Please ask question after putting your effort and please attach the way you have tried. Don't just copy paste question here.
