The length is determined by multiplying the number of balls with the diameter. The answer that would come out of this is in units of centimeters.
L = (6.02 x 10^23 balls)(4 cm/ball)
L = 2.408 x 10^24 cm
Then, we use the proper conversion factor to convert centimeter to kilometer.
L = (2.408 x 10^24 cm)(1 m/100 cm)(1 km/1000 m)
L = (2.408 x 10^24)(10^5)
The answer to this item is 2.408 x 10^19 km.

Step-by-step explanation:
Since, the polygon is a trapezoid made up of a rectangle and a right triangle. Therefore, according to the question, the figure of the polygon is attached.
Since, perimeter is the total length of the outer boundary of the figure. Therefore,
Perimeter of the polygon is


Area of the polygon = Area of Rectangle + Area of Triangle
