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

✔✔ Hence, it is solved ✅✅.

Answer 2

Answer:

25/4 cm

Step-by-step explanation:

isosceles triangle consists of 2 equal sides and a third unequal side.

therefore, given the data,

perimeter = 43/4

length of one of the equal sides = 9/4

third side = ?

perimeter = sum of all sides

     43/4    = 9/4 + 9/4 + x

43-18/4 = x

25 / 4= x

therefore, the third side measures 25/4 cm
