Step-by-step explanation:
In a rectangle L=11m, B=4.2m. since the semicircle is combined along it's breadth, diameter of semicircle is 4.2 then it's radius =4.2/2=2.1
perimeter of swimming pool is = perimeter of rectangle+circumference of semicircle
=2(L+B)+πr
=2(11+4.2)+(22/7)×2.1
=2×15.2+22×0.3
=30.4+6.6
=37m
