Step-by-step explanation:

area of triangle =?

side 1 =12cm

side2 =16cm

side 2 =20cm

S1×S2×S3=ANSWER

12×16×20=?

Answer 2

Answer:

s=(a+b+c)/2

s=(12+16+20)/2

s=48/2

s=24

by herons formula

area of triangle=√s(√s-√a)(√s-√b)(√s-√c)

=√24(√24-√12)(√24-√16)(√24-√20)

=√24(√12)(√8)(√4)

=√9216

=96
