Question

if the sides of triangel are 8cm, 11 cm and 13 cm then the area of triangel will be​

Answer 1

Answer:

The area of a triangle is sum of all sides

8cm+11cm+13 cm

32,,ans

Answer 2

Answer:

SEMI PERIMETER=s

s=(a+b+c)/2    (HERE, a,b and c are sides of triangle)

s=(8+11+13)/2

s=32/2

s=16

by heron's formula,

area= √(s(s-a)(s-b)(s-c))

a= √(16(16-8)(16-11)(16-13))

a= √(16*8*5*3)

a= √(4*4*2*2*2*5*3)

a= 4*2√(2*5*3)

a= 8√30

a= 8√30

THEREFORE, AREA OF TRIANGLE IS 8√30 cm²
