I would go with C

A:- Provides the ratio of length to breadth as 7x : 2x

B:- 2(L +B)=396 .... (L+B)=198

C:- Join A and B, Length = 7/9*198 = 154 ..... Breadth = 44

(1) The ratio of its length to its width is 7 to 2. Insufficient--length and width could be any two numbers satisfying this ratio.
(2) The perimeter of the playground is 396 meters. Insufficient--we don't know how the length and width are related.

Choice C--we can combine our knowledge of how the length and width are related with the perimeter to determine the dimensions.
