If the diagonal and the length of the perpendiculars from the vertices are given, then the area of the quadrilateral is calculated as: Area of quadrilateral = (½) × diagonal length × sum of the length of the perpendiculars drawn from the remaining two vertices.

Area=(1/2)×16×(5+5)=(1/2)×16×10=160÷2=80 cm^2.
