Question 1063946: Nine poles are erected on each side of boundary of a square
field.the distance between each pole is 80 m.what is the
perimeter of the field?

Even though there are 9 poles on each side, there are only
8 80-meter spaces between each pair of poles, as you see
below, where the numbers 1 through 9 represent the poles:


 1 80m 2 80m 3 80m 4 80m 5 80m 6 80m 7 80m 8 80m 9

Therefore the square field is 8×80m = 640m of each side.

Since a square has 4 sides, the perimeter is 4×640m = 2560m.
