To find the area of the quadrilateral, you need to find the area of the two triangles and add them,

Area(\quadrilateral ABCD) = Area(\triangle ADC \, + \triangle ABC)\\= \frac{1}{2}AC\times ED\, +\frac{1}{2}AC\times EB\\= \frac{1}{2}7AC\times (ED+EB)\\= \frac{1}{2}7.5\times (2+4)\\= 7.5\times 3 \\= \bf \underline{22.5\,cm^{2}}
