$\sf Let \: the \: third \: side \: be \: x. \\ \\ \because \sf x + \frac{9}{4} + \frac{9}{4} = \frac{4 3 }{4} \\ \\ \to \sf x + \frac{18}{4} = \frac{43}{4} \\ \\ \sf \to x = \frac{43}{4} - \frac{18}{4} \\ \\ \sf \to x = \frac{25}{4}$



$\huge \orange{ \boxed{ \boxed{ \sf{ \therefore x = \dfrac{25}{4}}}}}$



✔✔ Hence, it is solved ✅✅.

Answer 2

$<h1>Answer :-</h1>$

Given :- Perimeter of Triangle = $\dfrac{43}{4}$cm and

one of the side is $\dfrac{9}{4}$ cm


Let the third side be x.


$<u>According To Question :-</u>$


$\dfrac{9}{4}$ + $\dfrac{9}{4}$ + Third side = $\dfrac{43}{4}$


$\dfrac{18}{4}$ + x = $\dfrac{43}{4}$


x = $\dfrac{43}{4}$ - $\dfrac{18}{4}$


x = $\dfrac{25}{4}$


So, the measure of third side is :-

$\dfrac{25}{4}$ cm.
