Answer 1

Answer:

64 cm

Step-by-step explanation:

Refer the attached figure

In ΔABC

AB = AC since the given triangle is isosceles.

Base = BC = 24 cm

Altitude = AD

Area = 192 sq.cm.

Area of triangle =  

So,  

Thus AB =AC = 20 cm

BC = 24 cm

Perimeter of triangle = Sum of all sides

                                 = AB+BC+AC

                                 = 20+24+20

                                 = 64 cm.

Hence the perimeter of triangle is 64 cm.
