Solution
The correct option is A5m<a<125m It has been given that the park is triangular in shape, and we know that any triangle has the property that any two of its sides' sum should be greater than third side.
Now, in this question we know two sides are 60 m and 65 m.
So, the length of third side should be less than the sum of other two sides.
Hence, length of the third side is less than (65+60) m ⇒ Length of third side <125m
Also, 60m+a>65m ⇒a>5m
Hence 5m<a<125m
So, option(a) correct.
