Redraw the figure. The perimeter is the sum of all sides of the figure. This is a pentagon with three right angles, which means that the figure is the combining of a right triangle and a rectangle, as shown by the dotted line in the figure below. The unknown side of the figure is equal to the hypotenuse of the right triangle. The right triangle has legs of 5 and 12, which means the hypotenuse is equal to \(\sqrt{5^2+12^2}\). Add all the sides to get 17 + 5 + 12 + 17 + 13 = 64. The correct answer is (B).

90 degree and both the sides having same length indicates that if we draw a line to make the upper figure into a triangle, then its base and the base of the 2nd figure would be parallel and in fact be equal making it a rectangle. Using pythagoras theorem, we can get the side as 13. therefore 5 + 12 + 17 + 13 +17 = 64.
