Answer:
9. 775 square meters
10. 100,000 tablets
11. ₹105.35
Explanation:
9. You want the area of a rectangle 41 2/3 m by 18 3/5 m.
10. You want the number of 5 mg tablets that can be made from 0.5 kg of medicine.
11. You want the total spent if ₹60.20 was spent on biscuits and 3/4 of that amount was spent on toffees.
9. Area
The area is the product of the length and width:
A = LW
A = (41 2/3 m)(18 3/5 m) = 775 m²
The area of the park is 775 square meters.
10. Tablets
If n is the number of tablets that can be made, their total mass is ...
n(5 mg) = 0.5 kg
n = (0.5 kg)/(5 mg) = (500 g)/(0.005 g) = 100,000
100,000 tablets can be made from the medicine.
11. Spending
The total spending is the sum of the amounts spent on each item. The amount spent on toffees is 3/4 of the amount spent on biscuits, so the total is ...
₹60.20 + 3/4 · ₹60.20 = (1 +3/4)·₹60.20 = ₹105.35
Mr. Verma spent a total of ₹105.35.
