Question

find the area of a triangle if there and 22,21 and 29 cm

Answer 1

U can find the area or triangle by using herons formula

if u like it mark it as brilliant

Answer 2

s = 22 + 21 + 29 / 2

s = 72 / 2

s = 36

by using heron formula

area = √s ( s - a )( s - b)( s -c )

area = √36 (36- 22)(36-21)(36-29)

area =√36*14*15*7

area = √2*2*3*3*7*2*5*3*7

area =2*3*7*√30

area = 42√30cm²

hope this helps......
