Step-by-step explanation:
area of shaded region
area of square = a^2
a = 10
10 x 10
100 ---------1
area of circle = πr^2
22/7 x 1 x 1
22/7--------2
as there are 4 quadrant if we join them they make a circle
area of circle = πr^2
22/7 x 3 x 3
198/7--------------3
area of shaded region = 1 - 2 + 3
100 - 22/7 + 198/7

Answer:
saded part=square-4x sector+circle
Asquare=l×l
=10×10
=100
sector =0÷360×22÷7×3×3
90÷360×22÷7×9
1÷4×22÷7×9
22÷7×9÷4
area of 4 sector=4×22÷7×9÷4
=22÷7×9
Acircle=22÷7×2×2
=22÷7×4
so
unsaded area=22÷7×9+22÷7×4
=22÷7 (9+4)
22÷7×13
saded area=100-22÷7×13
=83.857
