Answer:
156 sq cm
Step-by-step explanation:
length of the rectangle = 16 cm
breadth of rectangle = 12 cm
area of rectangle = l × b
= 16 × 12
= 192 sq cm
inside figure is trapezium
parallel side are 4 cm and 8 cm
height is 6 cm
area of trapezium = 1/2 × h × (a + b)
= 1/2 × 6 × (4 + 8)
= 1/2 × 6 × 12
= 3 × 12
= 36 sq cm
area of shaded region =
area of rectangle - area of trapezium
= 192 - 36
= 156 sq cm
