The correct Answer is:
To find the length of the rectangular piece of land given its perimeter and breadth, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the formula for the perimeter of a rectangle**: The formula for the perimeter (P) of a rectangle is given by: \[ P = 2 \times (\text{length} + \text{breadth}) \] 2. **Substitute the known values into the formula**: We know the perimeter (P) is 424 m and the breadth (B) is 85 m. We can substitute these values into the formula: \[ 424 = 2 \times (\text{length} + 85) \] 3. **Simplify the equation**: Divide both sides of the equation by 2 to simplify: \[ 212 = \text{length} + 85 \] 4. **Isolate the length**: To find the length, subtract 85 from both sides: \[ \text{length} = 212 - 85 \] 5. **Calculate the length**: Now, perform the subtraction: \[ \text{length} = 127 \, \text{m} \] ### Final Answer: The length of the rectangular piece of land is **127 meters**. ---
