Answer 2

A triangle is drawn to circumscribe a circle and AD= 6cm, DB=4 cm, CF=3cm. The perimeter of triangle abc is 26 cm. Step wise explanation is given below:

It is given that the

AD=6cm

BD=4cm

CF=3cm

As we know that the tangents drawn from external point to a circle are equal.

So,AD=AF=6cm

BD=BE=4cm

CF=CE=3cm

By using these values

AB=AD+BD=6+4=10

BC=BE+CE=4+3=7

AC=AF+CF=6+3=9

By using the foumula of perimeter

P=AB+BC+AC

P=10+7+9

P=26cm
