If the tangent is drawn from the outside of the circle. Then the length of the tangents will be same. Then the perimeter is 30 cm.
What is the perimeter of a triangle?
Let the triangle be ABC. Then the perimeter of the triangle will be
Perimeter = AB + BC + CA
We know that if the tangent is drawn from the outside of the circle. Then the length of the tangents will be same.
Then the completed diagram is given below.
P = 3 + 3 + 3 + 3 + 9 + 9
P = 30 cm
