Question

the figure shown below represents a square piece of land with a circular grass bed in it's centre. Find the
a) area of the whole land.
b) area of the grass bed .
c) area of the land excluding the grass bed. ​

Answer 1

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
