C. 3a

D.

Answer :

It is given in the question that, equal sides of isosceles triangle is a

It is also given that, the given triangle is isosceles right-angled triangle


AC =


AC =


AC =


AC = a


We know that,


Perimeter of triangle = Sum of all sides


Perimeter = (AB + BC + AC)


= (a + a + a)


= 2a + a


= a (2 + )


Hence, option (b) is correct
