You have a quadrilateral that is made up of 4 triangles:
Triangles ABE, BEC, CED, and AED.
The angles that have veterx E, angles BEA, BEC, cED, and AED  are all right angles.
For each triangle, you have the lengths of the sides that form the right angle. That means you have the base and height. Find each area and add them all up.
