Answer 1

Answer:AREA OF WHOLE LAND

since its a square,area will be side^2

=10^2

=100

answer:100sq.m

AREA OF GRASS BED

area of a circle is given by pi×r^2

diameter is 6m therefore radius is 3m.

area= 3.14×3^2= 28.26

answer:28.26sq.m

AREA OF LAND EXCLUDING GRASS BED

it would be equal to area off whole land-grass bed

=100-28.26

=71.74

answer:71.74sq.m
