Total fence required for the swimming pool = 49m
Given,
Swimming pool Length: 11.5m
Width of swimming pool : 5m
Perimeter of rectangle : 2(L+W)
fence erect: 2m from the edged
Then fencing is erected 2m from the edge,
New Length :
11.5 m + 2 m + 2m = 15.5 m
New Width :
5 m + 2m + 2m = 9m.
Total required fencing = 2(L+B)
= 2(15.5 + 9)
= 2(24.5)
= 49m
Hence, Total fence required for the swimming pool is 49m.
