Answer» 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 Like my answer if you find it useful!

Answer»

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
