# 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)?

Result

x =  560 cm
y =  0

#### Solution:

$x = 2 \cdot \ (200+80) = 560 = 560 \ \text{ cm }$
$x > = 500 \ cm \ \\ y = 0$
