The perimeter of an isosceles right triangle is 14+14 sq rt 2. What is the length of the hypotenuse of the triangle?  Choose the correct choice from the following answers.
A) 5  B) 6  C) 7  D) 8  E) 9.899

Rationale: "side of triangle is a then perimeter = a + a + a . sqrt 2 ( right angle and pythagorus ) = 2 a + a . sqrt 2 = 14 + 14 sqrt 2 or , a . ( 2 + sqrt 2 ) = 14 ( 1 + sqrt 2 ) , a = 14 * ( 1 + sqrt 2 ) / 2 + sqrt 2 = 14 * 2.414 / 3.414 = then hypotenuse = 9.899 e"
Answer: E
