The sides of a triangle are a = 35 cm, b = 54 cm and c = 61 cm
Now, perimeter a + b + c = 25
⇒ S = 1/2 (35 + 54 + 61)
⇒ s = 75 cm
By using heron’s formula
The altitude will be a smallest when the side corresponding to it is longest Here, longest side is 61 cm.
Hence the length of the smallest altitude is 30.79 m
