$\fbox{ mark \: me \: brainliest and flw me :}$

Step-by-step explanation:

Swimming pool Length: 11.5m

Width: 5m

Perimeter formula: 2(L+W)

fence erect: 2m from the edgde

Then

Legth of the fencing: 11.5 m + 2 m + 2m = 15.5 m

Width of the fencing: 5 m + 2m + 2m = 9m.

Thus the perimeter is: 2(15.5 + 9)= 49 meters.
