Answer 1

Answer:

(a) Area of shaded region = 88 cm^2

(b) Area of unshaded region = 220 cm^2

Step-by-step explanation:

(a) Area of vertical shaded region = lxb

= 2*14 = 28 cm^2

Area of horizontal shaded region = l*b

= 3*22 = 66 cm^2

Area of rectangle in centre = l8b

= 3*2 = 6 cm^2

Total area of shaded region = Area of vertical region + Area of horizontal region - Area of rectangle in centre

= 28+66-6

= 88 cm^2

(b) Area of whole rectangle = l*b

= 22*14 = 308 cm^2

Area of unshaded region = Area of whole rectangle  - Area of shaded region

= 308-88

= 220 cm^2
