113.10

Step-by-step explanation:

The area of a sector with measure $\theta$ and radius is given by $A_{sec}=r^2\pi\cdot \frac{\theta}{360^{\circ}}$ .

What we're given:

of 12 $\theta$ of $90^{\circ}$

Substituting given values, we get:

$A_{sec}=12^2\pi\cdot \frac{90}{360},\\\\A_{sec}=144\pi\cdot \frac{1}{4},\\\\A_{sec}\approx \boxed{113.10}$
