Question

a triangle ABC has three sides A=14m, B=13m&C=12.5m.find the area of triangle from hero's formula with explain​

Answer 1

Answer:

74.548m approx

Step-by-step explanation:

s = (a+b+c)/2

= (14+13+12.5)/2

= 19.75

Area of the triangle = root[ s(s-a)(s-b)(s-c) ]

= root[ 19.75(19.75-14)(19.75-13)(19.75-12.5) ]

= root [ 19.75 * 5.75 * 6.75 * 7.25 ]

= root [5557.465]

= 74.548
