From Statement II.
Suppose, side of a square be x.
Hence, x2 = 196
∴ x = 14 cm
From Statements I and II,
Radius of semi-circle, r = 7 cm
∴ Circumference of semi-circle
πr = 22/7 x 7 = 22 cm
Hence, both Statement are required .Correct Option: E

From Statement I.
n = W + 6
From Statement II,
p = w + 4
The value of w is not given.
So, exact average can't be determined .Correct Option: D
From Statement I.
n = W + 6
From Statement II,
p = w + 4
The value of w is not given.
So, exact average can't be determined .
