💡 Solution & Explanation

1 1 1 2 1 1 2 b 3 a 0, b 32, a a b 48, b 16 2 2        3 3 3 16 a 48 16 72, b 8 2 2       So the three loops from i 1  to i 3  are alike. x x' y y' O Now area of thi loop (square) 1 2  (diagonal)2    2 2 i i i 1 A 2b 2 b 2   So,    2 i 1 i 1 2 i i 2 b A 1 A 4 2 b    So the areas form a G.P. series So, the sum of the G.P. upto infinite terms.   2 1 1 1 A 2 32 1 1 r 1 4          2 2 4 8 2 32 32 3 3     square units.
