Answer :

Let the sides of the triangle ABC be:

a = 40 cm, b = 80 cm and c = 60 cm


s =


=


=


= 90 cm


Now, by using Heron’s formula we get:


Area of


=


=


=


= 30 × 10


= 300 × 3.87


= 1161 cm2


As we know that, the diagonal of a parallelogram divides it into two triangles of equal areas


Area of parallelogram (ABCD) = 2 × Area of ()


= 2 × 1161


= 2322 cm2
