Question

find the area of triangle whose sides are 123cm 234cm 126cm​

Answer 1

Answer:

area of triangle = √ s(s-a)*(s-b)*(s-c)

Step-by-step explanation:

s =a + b+ c/2

s= 123+234+126/2

s= 483/2

s=241.5

area of triangle =√ s(s-a)(s-b)(s-c)

√241.5*(241.5-123)*(241.5-234)(241.5-126)

√241.5*118.5*7.5*115.5.

= 4978.96
