Question

flag poles are to be erected at equal spaces along the boundary of a rectangular playground of length 156m and breath 84 such that each corner has a flag.find the minimum no. of flags that will be needed

Answer 1

hey dude ........
ur answer is here......??????

let's factorize the length and width of your rectangle.

156=2x2x13x3.

84=2x2x3x7.

We’ve got 7 segments of our lowest common denominator to separate on the width, and 13 on the length.
now,,
We have two lengths and 2 widths.
then,
double the sum of that is 40.
Since,
the flags and our lowest common segments are interspersed one-after-another..
the flag number and the segment number match at 40.

hope it will help.....

thanks......!
