Question

find the area of the triangle whose side are 13,14,15 cm


please write it in a copy and explain if possible ​

Answer 1

Answer:

Area is 84cm2

Step-by-step explanation:

Given sides of triangle

a=13,b=14,c=15

Semi-perimeter s=21(a+b+c)=21(13+14+15)=21

Area, A = s(s−a)(s−b)(s−c)

A=21(21−13)(21−14)(21−15)

A=84 cm2
