• A. $500$
• B. $400$
• C. $900$
• D. $625$

Answer 1

Answer: (D)

$625$

Since the poles are planted along the perimeter and at a distance of $5m$ each.

Also no. of poles $=20$

So, side of square field $=25m$

Now, Area of square field $={\text{side}}^2$

$\Rightarrow {25}^2=625$

so, area of given square field is $625m^2$.
