Answer 1

Answer:

Rs. 7200

Appropriate Question:

Find the cost of ploughing a rectangular farm of length 400 m and breadth 300 m at Rs. 6 per 100 square metres.

Solution:

Accroding to the provided information in the given question, we have :

• Length of rectangular farm = 400 m

• Breadth of rectangular farm = 300 m

• Cost of ploughing per 100 m² = Rs. 6

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

As ploughing is done on the whole surface of the farm, so we need to calculate the area of the rectangular farm. Since, the farm is in rectangular shape. So, we'll apply the area of rectangle to calculate its area.

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

⇒ Area of farm = Length × Breadth

⇒ Area of farm = 400 m × 300 m

⇒ Area of farm = 120000 m²

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, area of the park is 120000 m².

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

As in the question we are given that cost of ploughing per 100 m² is Rs. 6. So,

⇒ Cost of ploughing 1 m² = Rs. $\sf \dfrac{6}{100}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

If cost of ploughing 1 m² is Rs. $\sf \dfrac{6}{100}$, then :

⇒ Cost of ploughing 120000 m² = Rs. $\sf \dfrac{6}{100}$ × 120000

⇒ Cost of ploughing 120000 m² = Rs. $\sf \dfrac{6}{1}$ × 1200

⇒ Cost of ploughing 120000 m² = Rs. 7200

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

Therefore, the cost of ploughing the rectangular farm is Rs. 7200.
