14. A parallelogram is circumscribed about a circle. The lengths of its diagonals are 30 cm and 16 cm. The perimeter of the parallelogram is?

• the parallelogrm is here a rhombos..so two diagonals intersect each other at 90 degrees
  so we get 4 right angled triangles whose two sides are (30/2)=15 & (16/2)=8
  so the other side is=root(15^2+8^2)=17
  so perimeter is =4*17=68.......
