hello mate..

I have given a hint

you solve ok

Answer 2

Answer:

Length of the third side is 5.35 cm

Step-by-step explanation:

Given :

Two sides of a triangle are :-

$1.) \: 3 \frac{2}{5} = \frac{17}{5} = 3.4cm$

$2.) \: 5 \frac{1}{4} = \frac{21}{4} = 5.25cm$

Perimeter of the triangle = 14cm

Let the length of the third side be a cm

We know that,

Perimeter of triangle = Sum of the length of side of triangle.

--> 3.4 + 5.25 + a = 14

--> 8.65 + a = 14

--> a = 14 - 8.65

--> a = 5.35 cm

I hope it helps u dear friend ^_^♡♡
