Find the square root of the area and yiull get the answer
N76 [4]2 years ago
4 0

Since each one is a square, each side has to be the same length. I know that 12×12 is 144, so for the first square, each side is 12 inches. Then, use the formula to determine the perimeter. 4×12=48, so the first perimeter is 48 inches. For the second, I know that 9×9=81, so each side is 9. 4×9=36, so the perimeter is 36. For the last, each side is 18 inches. 4×18=72, so the perimeter is 72 inches.

Consider the 1-to10^19 scale on which the disk of the Milky Way Galaxy fits on a football field. On this scale, how far is it fr
bezimeni [28]

Beautiful !  What a great exercise !  I won't even check to verify
that 1:10⁻¹⁹ is an appropriate scale to map the Milky Way onto a
football field.  I'll just accept it and go from there.

(4.4 light years) x (10⁻¹⁹) = (2.5848 x 10¹³ miles) x (10⁻¹⁹)

                                       =  2.5848 x 10⁻⁶ mile

                                       =    0.164 inch .

(1,391,400 kilometers) x (10⁻¹⁹) = 1.3914 x 10⁻¹⁰ meter


Research Conclusions:

If the Milky Way shrinks to fit on a football field, then

-- Alpha Centauri is  0.164 inch from us.

-- The sun's diameter is about 1.39 times that of a Hydrogen atom. 

Playing with this same fun concept a little more:

-- The Earth is sailing around in its orbit, once a year,
    about 0.000015 millimeter from the sun. 

-- It takes light almost 27 years to travel 1 inch !

wow  !
