Answer 1

I can be find by using herons formula wait a minute

Answer 2

QuestioN :-

Find the area of triangle whose sides are 3 cm , 4 cm , 5 cm .

AnSWeR :-

Semi Perimeter = a + b + c / 2

=> 3 + 4 + 5 /2

=> 12/2

=> 6 cm

Using heron's formula , we will find the area of triangle

=> √ s( s - a ) ( s - b ) ( s - c )

=> √ 6 ( 6 - 3 ) ( 6 - 4 ) ( 6 - 5 )

=> √6 × 3 × 2

=> √36

=> 6 cm²

Hence , the area of triangle is 6cm²
