Question

Area of the square is half hectare what is its diagonal

Answer 1

the value of half hectare = 5000 sq. meters
so,
area of square = side × side
side2 (side square) = 5000
side= 50_/2 (50 under root 2)
now,
diagonal of square=_/side2 + side2 (under root side square + side square)
it implies that= (50_/2)2 + (50_/2) 2... (50 under root 2 square + 50 under root 2 square)
=5,000+5,000 = 10,000.
=100_/2 (100 root 2) = ans
