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 foot squared is one quarter of a square foot (36 square inches).
a number can only be square if it has a square root.
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.
A square has only to diagonals and either one will divide it in half.
(a - b)2 = a2 - 2ab + b2 square ft
The answer is C. Since B is one half step up from B flat, and C is one half step up from B, and two halves make a whole :)
One half?
(a+b)(a-b)
61.75 square feet. Multiply length by width - the result is the area in square feet.
if B*B = a, then B is square root of a
18.5 square feet = 2664 square inches
