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

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

✔✔ Hence, it is solved ✅✅.

Answer 2

Answer:

25/4 cm

Step By Step Explanation:

Let the required third side be x cm.

According To The Condition:

⇒ x + 9/4 + 9/4 = 43/4

⇒ x + 18/4 = 43/4

⇒ x = 43/4 - 18/4

⇒ x = 25/4
