Answer 2

See attached pic (Created my me)

Area of quadrant = $\bf\huge\frac{1}{4} \pi r^{2}$

Area of quadrant = $\bf\huge\frac{1}{4} \times3.14\times6^{2}$

Area of 4 quadrant = $\bf\huge 4\times\frac{1}{4} \times3.14\times36$

= 3·14 × 36

= 113·04 cm^2

Area of shaded region = Area of square  – Area of 4 Quadrant

= 144 – 113·04

Area of shaded region = 30·96 cm^2
