Answer 1

Answer:

38cm^2

Step-by-step explanation:

area of rectangle = lb

= 16 ×12

= 192 cm^2

now area of shaded region is equal to area of a circle of radius 7cm ( since when those 4 shaded regions are joined gives a cirle )

area of a circle = 22/7(pie) r^2

= (22/7) 7^2

= 154 cm^2

now area of unshaded region = area of rectangle - area of circle ( shaded region )

area of unshaded region = 192-154

= 38cm^2
