of triangle ABC is less than how many centimetres ?​

Answer 1

Answer:

perimeter must be less than 11

Step-by-step explanation:

Answer 2

Perimeter of triangle is less than 22 cm.

Step-by-step explanation:

In triangle ABC

AB=5 cm and BC=6cm

AB+BC=5+6=11cm

Perimeter of triangle ABC=AB+BC+AC

We know that if three sides of triangle are formed  triangle then sum of any two sides of triangle is greater than third side.

By using this property

AB+BC>AC

AC<11 cm

Adding both sides AB and BC

AB+BC+AC<11+AB+BC

Perimeter of triangle ABC<11+11=22cm

Perimeter of triangle is less than 22 cm.
