Answer:

$11\frac{13}{30}$

Step-by-step explanation:

we have

$7\frac{3}{10}+4\frac{2}{15}$

step 1

Convert mixed number to an improper fraction

$7\frac{3}{10}=7+\frac{3}{10}=\frac{7*10+3}{10}=\frac{73}{10}$

$4\frac{2}{15}=4+\frac{2}{15}=\frac{4*15+2}{15}=\frac{62}{15}$

step 2

Adds the fractions

$\frac{73}{10}+\frac{62}{15}=\frac{73*3+62*2}{30}=\frac{343}{30}$

step 3

Convert to mixed number

$\frac{343}{30}=\frac{330}{30}+\frac{13}{30}=11\frac{13}{30}$

Answer:

a) $A_{f} = 408.54\,m^{2}$ , b) $A_{w} = 106.2\,m^{2}$

Step-by-step explanation:

a) The floor area of the pool is:

$A_{f} = (10\,m)\cdot (12\,m)+(18\,m)\cdot (16.03\,m)$

$A_{f} = 408.54\,m^{2}$

b) The total area of the walls of the pool is:

$A_{w} = 2\cdot (0.9\,m)\cdot (16\,m) + (0.9\,m)\cdot (16\,m) + (18\,m)\cdot (1.8\,m)+ 2\cdot (12\,cm)\cdot (0.9\,m)+(10\,m)\cdot (0.9\,m)$

$A_{w} = 106.2\,m^{2}$
