Work Step by Step

It is known that the two points tangent to a circle from a point outside the circle are congruent. Thus, it follows that the perimeter is: $$ \left(8\right)\left(2\right)+\left(16\right)\left(2\right)+\left(6\right)\left(2\right)+\left(9\right)\left(2\right) \\ 16+32+12+18\\ 78$$
