Answer:

9 cm^2

Step-by-step explanation:

If the perimeter of the square is 12 cm, then the length of ONE side is (1/4) of that, or 3 cm.

The area of this square is A = s^2, where s is the length of one side.

Here we have A = (3 cm)^2 = 9 cm^2.

Sergio039 [100]

Answer:

$\frac{2x^2-3x}{7}$

Step-by-step explanation:

$\frac{2x-3}{x}$ ÷ $\frac{7}{x^2}$

=> $\frac{2x-3}{x}$ × $\frac{x^2}{7}$

=> $\frac{2x-3}{7}$ × $\frac{x^2}{x}$

=> $\frac{x(2x-3)}{7}$

=> $\frac{2x^2-3x}{7}$
