Answer 2

Answer:

Step-by-step explanation:

We know that sum of two sides of triangle is aways greater than third side.

∴BC<AB+AC

And AB +BC>AC

⇒BC>AC−AB

Therefore, AC−AB < BC < AB+AC

⇒3−0.5<BC<3+0.5

⇒2.5<BC<3.5

As, the length of BC is integral value

Therefore, BC=3 cm

∴a=3 cm, b=3 cm and c=0.5 cm

Therefore length of median from vertex A is
