A square garden has sixteen posts along each side at equal interval. Find how many posts are there in all four sides: (A) 64 (B) 58 (C) 62 (D) 60
Read Solution (Total 4)
-
- No. of sides in a Square = 4
No. of Posts on each side = 16
Total Posts = No. of sides × No. of posts on each side - No. of vertices of a Square
⇒ Total Posts = 4 *16-4 =>4*15=60. - 5 years agoHelpfull: Yes(6) No(0)
- 4n-4 = 4*16-4=60

- first side has 16 posts , second and third sides have 15 posts on each side (16-1=15)(i.e. one post is already placed and can be used for another side and last side is (16-1-1=14) . so , 16+15+15+14=60
answer = 60 - 4 years agoHelpfull: Yes(2) No(0)
