• A. 500
• B. 400
• C. 900
• D. None of these

Answer 1

The correct option is D None of these

20 poles are used at a distance of 5 meters of each other then there are four poles in each line of square and 4 poles are at the corner of the square.

Then according to the question length of each Side of square $=25$ meters

Then area of the square $=\left({25}^2\right)=625m^2$
