Answer 2

${\huge\star{\mathfrak{\underline{\underline{Answer:}}}}}$

To get the desired answer, firstly we will find the perimeter of square garden and then divide the distance between posts from perimeter of Square garden.

Now,

Side of square = 10m

Perimeter of square = 4×side

=> 4×10 = 40m

Now,

Distance between posts = 2m

Number of posts = $\frac{40}{2}$

= 20

Thus, we find that number of posts required of fencing is 20.
