Flowerbed

The flowerbed has a length 3500mm and a width 1400mm. How many foil is needed to covers the flowerbed? How many m2 of foil was consumed for its production (add 10% of the material to the joint and waste)? How many liters of air is inside the enclosure? (Flowerbed height is 1 dm)

Result

S1 =  4.9 m2
S2 =  6.468 m2
V =  490 l

Solution:

$a=3500/1000=\dfrac{ 7 }{ 2 }=3.5 \ \text{m}^2 \ \\ b=1400/1000=\dfrac{ 7 }{ 5 }=1.4 \ \text{m}^2 \ \\ c=100 /1000=\dfrac{ 1 }{ 10 }=0.1 \ \text{m}^2 \ \\ S_{1}=a \cdot \ b=3.5 \cdot \ 1.4=\dfrac{ 49 }{ 10 }=4.9 \ \text{m}^2$
$S=S_{1} + c \cdot \ (2 \cdot \ a+2 \cdot \ b)=4.9 + 0.1 \cdot \ (2 \cdot \ 3.5+2 \cdot \ 1.4)=\dfrac{ 147 }{ 25 }=5.88 \ \\ S_{2}=(1+10/100) \cdot \ S=(1+10/100) \cdot \ 5.88=\dfrac{ 1617 }{ 250 }=6.468 \ \text{m}^2$
$V=1000 \cdot \ S_{1} \cdot \ c=1000 \cdot \ 4.9 \cdot \ 0.1=490 \ \text{l}$
