Question

Answer 1

\(S_{xq}=\left(1.8+1.6\right)\cdot2\cdot0.6=4.08\left(dm^2\right)\)

\(S_{tp}=4.08+2\cdot1.8\cdot1.6=9.84\left(dm^2\right)\)

Answer 2

\(Sxq=\left(1,8+1,6\right)\times2\times0,6=4,08\left(dm^2\right)\\ Stp=4,08+\left(1,8\times1,6\times2\right)=9,84\left(dm^2\right)\)

Answer 3

Sxq=(1.8+1.6)⋅2⋅0.6=4.08(dm2)Sxq=(1.8+1.6)⋅2⋅0.6=4.08(dm2)

Stp=4.08+2⋅1.8⋅1.6=9.84(dm2)

Answer 4

 

Sxq=(1.8+1.6)⋅2⋅0.6=4.08(dm2)

Stp=4.08+2⋅1.8⋅1.6=9.84(dm2
