You can cancel off the B and C

hwyl · Answer

AREA IS ALWAYS TO THE SECOND POWER SINCE IT IS A "SQUARED" OF TWO DIMENSIONS - THE LENGTH AND WIDTH - THAT HAVE THE SAME MAGNITUDE.

hwyl · Answer

SO IF THE LENGTH IS 2 METERS, IT MEANS THAT THE WIDTH MUST BE ALSO 2 METERS SINCE IT IS THE DEFINITION OF A SQUARE.  THEREFORE, $2 m \times 2 m = 4 m^2 $

But the area of a square is calculated by:
$\large \text{Length} \times \text{Width}$

calculusxy · Answer

or simply 
$\text{(Side)}^2$

i do not know

calculusxy · Answer

A square has all of its sides congruent (equal). Therefore, since we know one side length being 30in. we can know that the remaining sides are also 30 inches.|dw:1458494864393:dw|

calculusxy · Answer

Just know that every side of the square is equal. If one side is 30 inches, then all of the sides are 30 inches as well.
