Answer:
Please check the explanation.
Step-by-step explanation:
Given
- The length of rectangular field = l = 240m
- The breadth of rectangular field = w = 200m
We can determine the area of the rectangular field using the equation

where
is the length
is the width
substituting l = 240m, and w = 200m in the formula

A = 240 × 200
A = 48000 m²
Given that the cost of digging the field at Rs 10 per m².
Thus,
The cost of digging the field of the area 48000 m² = 10 × 48000
= 480000 Rs
Therefore, the total cost of digging = 480000 Rs
