Match List – I with List – II.

Choose the correct answer from the options given below:

A-III, B-II, C-I, D-IV

A. Perimeter of Right angled isosceles triangle with side ‘a’

H² = P²+ B²

= a² + a²= 2a²

H = a√2

Perimeter =  $2 a+\sqrt{2} a$ (III)

B. Area of parallelogram = base × height (II)

C. Area of a ring with $r_1$ and $r_2$ as radius of inner and outer circle

= π ( r2² - r1²) (I)

D. Area of equilateral triangle with side ‘a’  = $\frac{\sqrt{3}}{4} a^2$  = (IV)

The correct answer is Option (2) → A-III, B-II, C-I, D-IV
