Length of rectangular lawn = 10 m, breadth of the rectangular lawn = 5 m And radius of the circular flower bed = 2 m
(i) Area of the whole land = length x breadth
= 10 x 5 = 50 m2
(ii) Area of flower bed = πr 2
= 3.14 x 2 x 2 = 12.56 m2
(iii) Area of lawn excluding the area of the flower bed = area of lawn – area of flower bed
= 50 – 12.56
= 37.44 m2
(iv) The circumference of the flower bed = 2πr
= 2 x 3.14 x 2 = 12.56 m
