Answer:
a) [tex]A_{f} = 408.54\,m^{2}[/tex], b) [tex]A_{w} = 106.2\,m^{2}[/tex]
Step-by-step explanation:
a) The floor area of the pool is:
[tex]A_{f} = (10\,m)\cdot (12\,m)+(18\,m)\cdot (16.03\,m)[/tex]
[tex]A_{f} = 408.54\,m^{2}[/tex]
b) The total area of the walls of the pool is:
[tex]A_{w} = 2\cdot (0.9\,m)\cdot (16\,m) + (0.9\,m)\cdot (16\,m) + (18\,m)\cdot (1.8\,m)+ 2\cdot (12\,cm)\cdot (0.9\,m)+(10\,m)\cdot (0.9\,m)[/tex]
[tex]A_{w} = 106.2\,m^{2}[/tex]
