"The sides with this length does not perform the triangle."The sides with this length does not perform the triangle.
b+c < ab+c<a

Explanation:

Let triangle ABC ABC be the triangle with

a=14,b=9 and c=4a=14,b=9andc=4

The perimeter of triangle is:

2s=a+b+c=14+9+4=27=>s=27/2=13.52s=a+b+c=14+9+4=27s=272=13.5

:.s-a=13.5-14=-05

So, let us check three sides of triangle.

(i)a+b=14+9=23> c

(ii)b+c=9+4=13 < ato[as a=14]

Hence , the sides with this length does not perform the
triangle.
