Given sides of a parallelogram are 12 m , 17th
then area of parallelogram =?
Let a=12m b=17m
Area of parallelogram =a×b
=12×17
=204 m^2
then area of parallelogram =?
Let a=12m b=17m
Area of parallelogram =a×b
=12×17
=204 m^2

by heron's formula
area = (sqrt(27(27-12)(27-17)(27-25))×2 = 180m(square)
area = (sqrt(27(27-12)(27-17)(27-25))×2 = 180m(square)
But is for triangle
This formula is for triangle
paralellogram consists of two triangles you idiot
Yes i forgot
