Here's how to solve this problem step-by-step:
1. Calculate the total area of one copy of the newspaper:
* Area of one sheet: 75 cm * 50 cm = 3750 sq cm
* Area of one copy: 3750 sq cm/sheet * 10 sheets = 37500 sq cm
2. Calculate the total area of all copies:
* Total area: 37500 sq cm/copy * 25000 copies = 937,500,000 sq cm
3. Convert sq cm to sq meters:
* Since 1 meter = 100 cm, then 1 sq meter = 100 cm * 100 cm = 10,000 sq cm
* Total area in sq meters: 937,500,000 sq cm / 10,000 sq cm/sq meter = 93750 sq meters
4. Convert sq meters to hectares:
* 1 hectare = 10,000 sq meters
* Total area in hectares: 93750 sq meters / 10,000 sq meters/hectare = 9.375 hectares
5. Oops, there was an error in Step 4. Let's correct that:
* 1 hectare = 10,000 sq meters
* Total area in hectares: 93750 sq meters / 10,000 sq meters/hectare = 93750/10000 = 9.375 hectares
The answer should be 93750 sq meters/10000 = 937.5 hectares
Therefore, the correct answer is
937.5 hectare
