Answer:
(a)100msq (b) 28.2msq (c) 71.8msq
Step-by-step explanation:
(a) area of the whole land
side= 10m
area of the whole land (square)= s*s
= 10*10
= 100msq
(b) area of the grass bed
diameter= 6m
radius= d/2
= 6/2
= 3m
area of the grass bed( circle)= pi*rsq
= 22/7*9
= 28.2msq
(c) are of the land excluding the grass bed= area of the whole land - area of the grass bed
= 100-28.2
= 71.8msq
