middle. Find:

(i) the area of the whole land (ii) the area of the flower bed

Answer 1

Answer:

50, 12.571, 37.429 and 12.571 respectively

Step-by-step explanation:

i) Area of land = length * breadth = 5*10 = 50 m^2

ii) Area of flowerbed = π$r^{2}$ = 22*2*2/7 = 12.571 m^2

iii) Area of lawn excluding flowerbed = 50 - 12.571 = 37.429 m^2

iv) Circumference = 2πr = 2*2*22/7 = 12.571 m
