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

✔✔ Hence, it is solved ✅✅.

Answer 2

Answer:

Step-by-step explanation:

Given Perimeter = 43/4 cm

Each of the equal sides is = 9/4 cm

According to the question,

2(9/4) + x = 43/4, where x is the measure of the third side.

x = 43/4 - 18/4 = (43-18)/4 = 25 /4 cm

Hence, the measure of the third side is 25 / 4 cm.
