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
