Answer 2

Answer:

The sides of the triangle are:

2.8 cm, 5.6 cm,5.6 cm.

Step-by-step explanation:

The perimeter of an isosceles triangle is given=14 cm.

Now in an isosceles triangle the length of two sides are equal and the third side is unequal.

Now,it is given that:

One of its sides is twice longer than another of its sides.

As we know that in any triangle with sides lengths a,b and c  must hold that:

a<b+c and b<a+c and c<b+a

So, the equal sides are '2x 'and the unequal side is 'x'.

Hence, as we are  given the perimeter of the triangle that means:

x+2x+2x=14

5x=14

x=14/5=2.8 cm.

So, the sides of the triangle are:

2.8 cm, 5.6 cm,5.6 cm.
