     Define a function hypotenuse (a, b) which returns the length of the hypotenuse c, if the other two sides have lengths a and b.  Recall that the perimeter of a triangle is the sum of the sides. So in the diagram above, the perimeter has length a + b + c. Your program should assume that a correct version of hypotenuse has already been defined (you don\'t need to copy it from the first box to the second).  Using hypotenuse(a, b), define a function right Triangle Perimeter (a, b) which returns the length of the perimeter in a right triangle whose non-hypotenuse sides have lengths a and b. 
  
  Solution
def rightTrianglePrimeter(a,b):
//formula to find perimeer of right angled triangle
p=a+b+ sqrt((a*a)+(b*b))
return p
