Question

Find the area of the triangle in which a=13m,b=14m and c=15m

Answer 1

This is the right answer

Answer 2

Step-by-step explanation:

AREA OF TRIANGLE ABC=√(s-a)(s-b)(s-c)SQ unit

=s1/2(a+b+c)

1/2(13+14+15)

1/2×42=21

(s-a)=(21-13)=8

(s-b=(21-14)=7

(s-c=(21-15)=6

Area of given triangle=√21×8×7×6m^2

=84m^2
