Question

A triangle has a perimeter of 9 cm. How many combinations of its sides exist, if their lengths in cm are integers?​

Answer 1

Answer:

Step-by-step explanation:

The sum of the three sides of triangle=9

Using condition that sum of 2 side of △ must be greater than 3rd.

We have only 2 choices (3,4,2)(5,3,3).

Answer 2

Answer:

perimeter of a triangle = A+B+C

let's consider the sides as X cm.

so, x + x + x = 9cm

3x = 9cm

therefore, x = 9/3 = 3cm
