We first determine the perimeter of the gym using the scaled numbers, that is:
[tex]p_s=5+4+5+4\Rightarrow p_s=18[/tex]
Now, since the scaled perimeter is of 18 cm, we then use the scale (1 cm = 10 m) to determine the total perimeter of the gym:
[tex]p=18\cdot10\Rightarrow p=180[/tex]
We will haave that the real perimeter of the gym is of 180 meters.
