Question

find the area of the shaded portions.​

Answer 1

Step-by-step explanation:

area of rectangle equal to L × B

then 30 ×50 = 150

and

40 × 20 =800

Answer 2

Answer:

700 m²

Step-by-step explanation:

Let the outer rectangle be ABCD

and the inner rectangle be PQRS

Area of shaded region = Ar[ABCD] - Ar[PQRS]

                                     = (50×30) - (20×40)

                                      = 1500 - 800

                                      = 700 m²
