The cost of fencing a `15 m xx 7m`  rectangular park at * 45 per metre is 

Options

A. Rs. 4275
B. Rs. 4725
C. Rs. 1980
D. Rs. 5427

Answer

To find the cost of fencing a rectangular park with dimensions 15 m by 7 m at a rate of Rs. 45 per meter, follow these steps:

### Step 1: Calculate the Perimeter of the Rectangle
The formula for the perimeter (P) of a rectangle is given by:
\[ P = 2 \times (\text{Length} + \text{Breadth}) \]

Here, the Length (L) is 15 m and the Breadth (B) is 7 m.

Substituting the values:
\[ P = 2 \times (15 \, \text{m} + 7 \, \text{m}) \]
\[ P = 2 \times 22 \, \text{m} \]
\[ P = 44 \, \text{m} \]

### Step 2: Calculate the Cost of Fencing
The cost of fencing is calculated by multiplying the total perimeter by the cost per meter.

The cost per meter is Rs. 45. Therefore, the total cost (C) is:
\[ C = \text{Perimeter} \times \text{Cost per meter} \]
\[ C = 44 \, \text{m} \times 45 \, \text{Rs/m} \]
\[ C = 1980 \, \text{Rs} \]

### Final Answer
The total cost of fencing the rectangular park is Rs. 1980.
