one (half acre) = 21 780 square foot
One square kilometer is 247.11 acres. Half that is 123.6 acres.
Area of a square = side2 Square A area = a2 Square B area = (4a)2 (4a)(4a) = 16a2 The area of square B is sixteen times the area of square A. Proof: Side of square A = 2 inches Side of square B = (4*2) = 8 inches Area of A = 22 = 4 square inches Area of B = 82 = 64 square inches 64 / 4 = 16
A number to the one half power is the square root.

One half mile times one half mile is equal to one quarter square mile.
one (half acre) = 21 780 square foot
One half foot squared is one quarter of a square foot (36 square inches).
a number can only be square if it has a square root.
pi*a*b where a = half length of major axis (horizontal) and b = half length of minor axis (vertical)
One square kilometer is 247.11 acres. Half that is 123.6 acres.
You cannot prove it because it is not necessarily true. A = 16 < B = 25 But one square root of A = +4 is not less than one square root of B = -5.
One half acre is equivalent to 21,780 square feet.
A square has only to diagonals and either one will divide it in half.
