Answer 2

The perimeter of the square shaped paddy field is 400 m. Hence, option (d) is correct.

• Given,

Area of the square shaped paddy field = 10,000 m²

• A square has all its sides equal. So, let each side of the paddy field be taken as x.

• The area of a square is given as : Area = side × side

Therefore, the area of the paddy field = x × x

=> 10,000 m² = x²

=> x = $\sqrt{10,000 \ m^{2} }$

=> x = $\sqrt{100 \ m \ . \ 100 \ m}$

=> x =  $100 \ m$

∴  Each side of the paddy field = 100 m

• Perimeter of a square field = 4 × side

∴  Perimeter of the square shaped paddy field = 4 × 100 m = 400 m
