Step-by-step explanation:

$\dfrac{3}{5}\\\\\text{list of multiples of 5}:0,\ 5,\ 10,\ 15,\ \boxed{\bold{20}},\ 25,\ 30,\ ...\\\\\dfrac{3}{4}\\\\\text{list of multiples of 4}:\ 0,\ 4,\ 8,\ 12,\ 16,\ \boxed{\bold{20}},\ 24,\ 28,\ ...$

$\dfrac{3}{5}=\dfrac{3\cdot4}{5\cdot4}=\dfrac{12}{20}\\\\\dfrac{3}{4}=\dfrac{3\cdot5}{4\cdot5}=\dfrac{15}{20}$

Answer:

$230.73m^2$

Step-by-step explanation:

$A=2a^2+4ah=2*4^2+4*4*4=96m^2$ (square prism)

$A=2\pi rh+2\pi r^2=2*\pi *4*9+2*\pi *4^2 = 326.73m^$ (cylinder)
