In triangle BEC by Heron's Formula you can find the area of triangle.
After getting the answer by Heron's Formula compare it with 1/2xbxh. This is to get the height of the triangle.
Since, the height of triangle= the height of trapezium.
Therefore, you can easily find the area as you have parallel sides and height.
