Answer:
Step-by-step explanation:
The answer should be 640,000 bc you are adding the square base. Squares are 4 sides so 4x 160=640. Kilometers are 1,000, so you multiply 640x1,000 to get your answer.
A pyramid has a square base. The perimeter of the base in kilometers is 0.640 kilometers.
Solution:
Given that pyramid has a square base
Each side of the base = 160 m
Need to determine perimeter of base in kilometer.
Perimeter of Square = 4 x length of side of square
Perimeter of square base having side as 160 meters = 4 x 160 = 640 meters
We need answer in kilometers
As 1000 meters = 1 kilometer
[tex]\begin{array}{l}{\Rightarrow 1 \text { meter }=\frac{1}{1000} \text { kilometers }} \\\\ {\Rightarrow 640 \text { meter }=640 \mathrm{x} \frac{1}{1000} \mathrm{kilometers}} \\\\ {\Rightarrow 640 \mathrm{meter}=0.640 \mathrm{kilometers}}\end{array}[/tex]
Hence perimeter of square base of pyramid having base side as 160 meters is 0.640 kilometers
