Mr thomas puts up fence posts from one end to another equal distances apart.there are 27 posts the width of each part is 10 centimeters. The distance between two posts is 30 meters find the length of the fence

Sagot :

If there are 27 posts, then there are (n - 1) total spaces between the posts . . . 27 - 1 = 26 total spaces (since there has to be a post at each end of the line)

Here's an example of 7 posts equally spaced . . . so you can see there are one less spaces between posts than there are posts (i.e. 6 total spaces between 7 posts) . . .

[] . . . [] . . . [] . . . [] . . . [] . . . [] . . . []

27 posts = 27*(10cm) = 270 cm = 2.7m
26 spaces = 26*(30m) = 780 m

Length of Fence = L = 780m + 2.7m = 782.7m
