You don’t have to figure out the legs of the right triangle. You just have to know the sum of the two legs.

Solve for AR + RC. It is given that length + width is 8.
Now solve for the diagonal line AC.
How? AC is given in a very subtle way. This one is very tricky. AC and RB(not shown) is the same length. RB is 6 because it’s a radius!

Find the arc ST.
12pi/4 = 3pi

Add the sides up… 12-8+6+3pi = 10 + 3pi
B is the correct answer.

I don’t think my explanation was clear for this one. Ask me again if you didn’t understand it.
