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

✔✔ Hence, it is solved ✅✅.

Answer 2

Answer:

25/4 cm

Step-by-step explanation:

Given the perimeter of the isosceles triangle is 43/4 cm .

We know that 2 sides of this kind of triangle is equal .

Hence let us say that those sides are a and the unequal one is b .

a + a + b = 43/4 cm

= 2 a + b = 43/4 cm

Now we are given that one of the side measures 9/4 cm .

Hence :

= 2 × 9/4 cm + b = 43/4 cm

= 18/4 cm + b = 43/4 cm

= b = 43/4 cm - 18/4 cm

= b = 25/4 cm

The third side is 25/4 cm .
