Question

find the area of which triangle in which a=13m, b=14m , c=15m​

Answer 1

Step-by-step explanation:

Given sides of triangle

a=13,b=14,c=15

Semi-perimeter s=

2

1

(a+b+c)=

2

1

(13+14+15)=21

Area, A =

s(s−a)(s−b)(s−c)

A=

21(21−13)(21−14)(21−15)

A=84 cm

Answer 2

Ans: 84 m

Explaination:

s=(13+14+15)/2

Area = root(s(s-13)(s-14)(s-15))
Root(7056)
84 m
