Answer 1

Answer:

a=2,b=6,c=4

Step-by-step explanation:

In a triangle,

the perimeter is equal to the sum of all the three sides

3x+2x+x=12

6x=12

x=2

Answer 2

Answer:

A triangle can be constructed with sides 6 cm, 4 cm and 2 cm.

Step-by-step explanation:

The formula to compute the perimeter of a triangle is:

P = a + b + c

Here a, b and c are sides of the triangle.

Let the sides of the triangle be 3x, 2x and x.

The perimeter is given as, P = 12 cm.

Compute the value of x as follows:

$3x+2x+x=12\\6x=12\\x=2$

The sides are:

$3x=3\times2=6\\2x=2\times2=4\\x=2$

Thus, a triangle can be constructed with sides 6 cm, 4 cm and 2 cm.
