Question

The rectangular field is $35m$ long and $18m$ wide. What is the cost of fencing it at $₹22.50permeter$?

• A. $₹2340$
• B. $₹2430$
• C. $₹2345$
• D. $₹2385$

Answer 1

The correct option is D

$₹2385$

The length of the rectangular field $\left(l\right)=35m$

The breadth of the rectangular field $\left(b\right)=18m$

The perimeter of the rectangular field $=2\times \left(l+b\right)$

$$\begin{gathered} =2\times \left(35+18\right) \\ =2\times 53 \\ =106m \end{gathered}$$

Now, the cost of fencing the rectangular field for $1m=₹22.50$

The total cost of fencing the rectangular field $=₹22.50\times 106$

$=₹2,385$

Hence, the total cost of fencing the rectangular field is $₹2,385.$

So, the correct option is D.
