    Step-by-step explanation:

    Given that,

    Length of rectangular lawn =10 m

    Width of rectangular lawn =5 m

    and

    radius of flower bed =2 m

    Part (1):

    The area of whole land = Area of rectangular lawn

    =length×width

    =10×5=50 m

    2

    The area of whole land =50 m

    2

    Part (2):

    Area of flower bed = Area of circle

    =πr

    2

    =3.14×2

    2

    ×=12.56 m

    2

    Area of flower bed =12.56 m

    2

    Part (3):

    The area of lawn excluding the area of the flower bed

    = rectangular lawn − Area of circle

    =50−12.56

    =37.44 m

    2

    The area of lawn excluding the area of flower bed =37.44 m

    2

    Part (4):

    Circumference of the flower bed = circumference of circle =2πr

    =2×3.14×2=12.56 m

    Circumference of the flower bed =12.56 m
