Solution

## The correct option is C 2,1,3 Consider the square and identify the two regions marked as I and II. Find the area of each unshaded region and subtract total areas of unshaded regions from the area of square Area of I region = Area of square - area of the lower quarter circle. Area of II region = Area of square - area of upper quarter circle. So, area of I = area of II = side2−14×πr2 =642−14×227×82 =13.72cm2 So, area of shaded region = area of square - area of I + area of II = 64 - 27.44 =36.56cm2   Suggest Corrections  0      Similar questions  Related Videos   Visualisations
