The door

The door to the apartment has a height 2 m and a width 80 cm. Calculate how many cm of sealing tape is needed to seal them. Will there be enough packaging in which there are 5 m tape (write 0 = no, 1 = yes)?

Correct result:

x =  560 cm
y =  0

Solution:

$x=2\cdot (200+80)=560\text{ cm}$

$$\begin{gathered} x>=500cm \\ y=0 \end{gathered}$$
