A rectangular swimming pool is 11,5m long and 5m wide.how many metres of fencing are needed to enclose the pool if you erect the fencing 2m from the edge

Answers

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.
