What is the perimeter of an isosceles right angled triangle. The area of the isosceles right angled triangle is 50. Options:
A) 25
B) 36
C) 25
D) 30
E) 34.14
An isosceles right angled triangle has both the base and height same.   The area of an isosceles triangle = 1/2 * base * height   since height = base   1/2 * height * height = 1/2 * height ^2 = 50   height ^ 2 = 100   height = 10 = base   Since we know the base and height. We will calculate the hypotenuse using Pythagoras   Base ^ 2 + Height ^ 2 = Hypotenuse ^ 2   10^2 + 10^2 = Hypotenuse^2   Hypotenuse^2 = 200   Hypotenuse = 14.14   Perimeter of the triangle = 10 + 10 + 14.14=
