For this case we must find the perimeter of the base of a square pyramid, whose side of the square measures 160m. In addition, the measure obtained must be converted to kilometers. So, we have by definition the perimeter of a square is the sum of its sides, which is equivalent to [tex]P = 4l[/tex], where "l" is the side of the square.
If[tex]l = 160m[/tex], then:
[tex]P = 4 * 160m\\P = 640m[/tex]
Thus, the perimeter of the base of the pyramid is 640m.
On the other hand, by definition: [tex]1Km = 1000m[/tex]
By making a rule of three we have:
1Km ---------> 1000m
x --------------> 640m
Where "x" represents the perimeter of the base of the pyramid in Km.
[tex]x = \frac {640 * 1} {1000}\\x = 0.64km[/tex]
Thus, the perimeter of the base of the pyramid is 0.64Km
Answer:
The perimeter in kilometers is 0.64
