"A)2(1+√2)/a",
"B)2(2+√2)/a",
"C)2(2+√2)/a",
"D)2(1+2√2)/a"
] | B | Explanation :
side of S1= a, perimeter of S1= 4a, area of S1 = a2
side of S2= a/√2 , perimeter of S2= 2√2a , area of S2 = a2/2
side of S3= a/2 , perimeter of S3= 2a , area of S3= a2/4
So, for P1 + P2 + P3 .... we will have a GP as below
4a + 2√2a + 2a + .....

P(2 orange) = 3/10 * 2/9 = 6/90
P(2 lemon) = 4/10 * 3/9 = 12/90
P(2 of the same flavor) = 24/90
P(2 different flavors) = 1 - 24/90 = 66/90 = 11/15
