as we can see in the square the are four quarters of circle.
if we multiply them, then
4×1/4=1circle
radius=7cm (given)
area of square = 14²
(as the radius is 7 the diameter [side] will be double of it)
= 196cm²
area of circle=πr²
=(22/7)×7×7
=22×7
=154
area of shaded part=area of square - area of circle
area of shaded part=196-154
=42cm²
option (1.)
