Question

two side of a triangle are 5 cm and 9cm long what can be the length of its third side

Answer 1

We know that, to form a triangle the sum of two side must be greater than third side.

So,

The maximum length of third side = (5+9) - 1 = 14 - 1 = 13 cm

Answer 2

the maximum Length of third side = 14-1 = 23 cm.
