Heya!!
========================================
HERON'S FORMULA
==================
Area of a triangle of sides a , b & c is :
√( s(s-a)(s-b)(s-c) )
where s=(a+b+c)/2
ln given trangle , s=(20+12+16)/2=48/2=24
Thus area of given triangle =
√(24(24-20)(24-12)(24-16))
=√(24×4×12×8)
=√9216
=96
Thus area of triangle of sides 20cm ,12cm and 16cm is 96cm^2
