Answer:
1km=1000m 160m=0.160x4=0.64
Step-by-step explanation:
Ifl = 160m, then:
P = 4 * 160m\\P = 640m
Thus, the perimeter of the base of the pyramid is 640m.
On the other hand, by definition: 1Km = 1000m
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.
x = \frac {640 * 1} {1000}\\x = 0.64km
Diagonals congruent: rectangle, square, isosceles trapezoid
Perpendicular bisectors: Rhombus, Square

Step-by-step explanation:
![8x + c = k\\\\8x + c-c = k -c \ \ \ \ \ \ \ \ \ [\ subtract \ c \ from \ both \ sides \ ]\\\\8x = k - c\\\\\frac{8x}{8} = \frac{k-c}{8} \ \ \ \ \ [ \ divide \ both \ sides\ by\ 8 \ ]\\\\x = \frac{k-c}{8}](https://tex.z-dn.net/?f=8x%20%2B%20c%20%3D%20k%5C%5C%5C%5C8x%20%2B%20c-c%20%3D%20k%20-c%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5B%5C%20subtract%20%5C%20c%20%5C%20from%20%5C%20both%20%5C%20sides%20%5C%20%5D%5C%5C%5C%5C8x%20%3D%20k%20-%20c%5C%5C%5C%5C%5Cfrac%7B8x%7D%7B8%7D%20%3D%20%5Cfrac%7Bk-c%7D%7B8%7D%20%5C%20%5C%20%5C%20%5C%20%5C%20%5B%20%5C%20divide%20%5C%20both%20%5C%20sides%5C%20%20by%5C%20%208%20%5C%20%5D%5C%5C%5C%5Cx%20%3D%20%5Cfrac%7Bk-c%7D%7B8%7D)
