Answer 1

Answer is 64
Hope it helps

Answer 2

Answer:

Given, base of an isosceles triangle =24 cm

Area of isosceles triangle =192 sq.cm

Area = 1/2 × b × h

192 = 24×h/2

h = 192×2/ 24

∴ h = 16 cm

Side= $\sqrt{h^{2} + 12^{2} }$

       = $\sqrt{256+144}$

       =20 cm

Perimeter of triangle =2a+b

=2(20)+24

=64 cm

Hence Solved.
