Answer 2

Step-by-step explanation:

Solution:

Side of the square = 4 cm

Radius of the circle = 1 cm

Four quadrant of a circle are cut from corner and one circle of radius are cut from middle.

Area of square = (side)2= 42 = 16 cm2

Area of the quadrant = (πR2)/4 cm2 = (22/7)×(12)/4 = 11/14 cm2

∴ Total area of the 4 quadrants = 4 ×(11/14) cm2 = 22/7 cm2

Area of the circle = πR2 cm2 = (22/7×12) = 22/7 cm2

Area of the shaded region = Area of square – (Area of the 4 quadrants + Area of the circle)

= 16 cm2-(22/7) cm2+(22/7) cm2

= 68/7 cm2
