# From each corner of a square of side 4 cm a quadrant of a circle of radius 1 cm is cut and also a circle of diameter 2 cm is cut as shown in Fig. 12.23. Find the area of the remaining portion of the square.

Each quadrant is a sector of 90° in a circle of 1 cm radius

Area of each quadrant = * r2

= * * (1)2

= cm2

Area of square = (Side)2

= (4)2

= 16 cm2

Area of circle = πr2 = π (1)2

= cm2

Area of the shaded region = Area of square - Area of circle - 4 × Area of quadrant

= 16 - - 4 *

= 16 - -

= 16 -

=

= cm2
