6 = 2x-12
18 = 2x
9 = x

4x-15 = 2x+3
2x-15 = 3
2x = 18
x = 9

Basically, x = 9

The formula for the area of a sector is

$k = \frac{m}{360} \times a$

Input the things which you already know. (m)

$k = \frac{45}{360} \times a$

a=πr^2

a=36π

Input this into the equation.

$k = \frac{45}{360} \times 36 \times 3.14$

$k = \frac{45}{360} \times 113.04$

$k = 14.13$
