Most high school algebra books show a proof (by contradiction) that the square root of 2 is irrational. The same proof can easily be adapted to the square root of any positive integer, that is not a perfect square. You can find the proof (for the square root of 2) on the Wikipedia article on "irrational number", near the beginning of the page (under "History").
because 2 times 2 = 4
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
√351 = 18.734993996 (Proof is 18.734993996 × 18.734993996 = 351.00000003)
A coordinate proof
the center of the figure at the origin
you can coordinate parallel because parallel lines never touch or cross
The unit of area "one square meter" or "one square foot" is DEFINED as the area of a square with sides of length 1 meter or 1 foot. This works for any unit of distance measurement. So we start with this definition. It follows that a square with sides of length n when n is an integer has area n2 square units because it can be divided into n*n= n2 small squares one unit on a side. For the area of a square with sides of fractional length, we can use a proof that calls upon similar polygons. This proves the area exists, it does NOT prove it is unique. To prove that, assume it is not uniqe and arrive at a contradiction.

the rabbit proof fence is 4,000,020 miles in length. i would know i measured it myself.
No, The volume of the cube would be the length multiplied by the length multiplied by the the length. Volume=Length X Length X Length (of a cube) V=L^3 The proof of this involves some work, but I'm assuming you don't want the proof behind this. http://www.math.com/tables/geometry/volumes.htm
A square is a four sided shape with equal sides and angles. The area is the length multiplied by the width, which is also the length squared or the width squared. Therefore: 4 x square-root(area) = perimeter. This formula only works for a square.This proof explains the above formula:s = side length, and a = area# s2 = a # s = sqrt(a) # 4s = 4[sqrt(a)] Step 1 is the basic formula for finding the area of a square.Step 2 takes the square root of both sides to give you the length of one side.Step 3 multiplies both sides by 4, because a square has 4 sides that need to be added to find the perimeter.

The only way I can think of is when the figure is a SQUARE with a length and width of FOUR. Proof: Perimeter of a square: One side multiplied by four. That would make it 4x4 which equals 16. Area of a square: lengthxwidth. That would also be 4x4.
