Answer 1

ar(shaded region) = ar(square)+2*ar(major sector)
= a^2+θ/360*πr^2 --- (θ=270)
$= 28 {}^{2} + 270 \div 360 \times \pi \times 14 \times 14$
=1708

Answer 2

Area of shaded region =area of square + 2 (area of circle ) - 2 (area of quadrant )

ar = 28×28 + 2×14×14×22/7 - 14×14×1/2 ×22/7
ar= 784+1232-308
ar=2016-308
ar= 1708
