sum to total side of a triangle /2
bibhubhusana1967:
it was to find semi perimeter
but say me the formula for finding area also
for area... underroot of (S-1st side) (S-2nd side) (S-3rd side)
Ok thanks
by mistake I forgot to give the formula of finding area
Ok no problem
also add S before (S-a)(S-b) (S-c)
ok
ya
Ok you ask one easiest question on brainly I will answer it you mark me as brainlieist then i will mark your answer as brainlieist answer ok

Heron's formula gives the area of the triangle without the use of base or altitude.
Given the sides of a triangle a, b,c
Then perimeter = a + b + c
Semi perimeter, s = ( a + b + c)/2
Now area = √s( s- a)(s - b)( s - c)
You can find the area of the triangle by heron's formula if all it's sides are known
