Question

If the perimeter of a square is 3x, what is the area of the square in terms of x?

Answer 1

Each side is (3x)/4 or 0.75x so the area is (0.75x)^2 or 9x/16

Answer 2

Perimeter of square: sum of all sides.
A square has 4 sides, obviously.
So each side would be: 3x/4
Then take square of the side to find area:
\[(3x/4)^{2}\]
Which gives us, \[9x ^{2}/16\]
That is the final answer.
