Answer:

(i) area of flower bed = 154m²

(ii) quantity of fertilizer required = 154 kg

(iii) total cost of fertilizer = Rs 1500

(iv) area in mm² = 1.54× [tex]10^{8}[/tex] mm²

Step-by-step explanation:

(i) given, radius = 7m

area of the flower bed = πr² = [tex]\frac{22}{7}[/tex]×7² =154m²

(ii) 1kg fertilizer is required for 1sq.m area

∴ quantity of fertilizer required = 154 kg

(iii) given, 1kg fertilizer costs Rs 10

total cost of fertilizer = 10× 154 = Rs 1500

(iv) area of flower bed = 154 m²

1m² = 1000000mm²

154m² = 154000000mm²

= 1.54×[tex]10^{8}[/tex]mm²
