Question

A rectangular plot of land is $300$ $m$ long and $250$ $m$ broad. The cost of fencing is $₹40$ per meter. What is the cost of fencing the entire field?

Answer 1

Step 1: Finding perimeter of rectangular plot

Length of the rectangular plot of land $=300m$

and breadth of the rectangular plot of land $=250m$

The perimeter of the rectangular plot of land

$$\begin{gathered} =2(l+b) \\ =2(300+250) \\ =2\times 550 \\ =1100m \end{gathered}$$

Step 2: Finding cost of fencing

Cost of fencing the entire field

$=$Perimeter of field $\times$cost per meter

$$\begin{gathered} =1100\times 40 \\ =₹44,000 \end{gathered}$$

Hence, cost of fencing the entire field is $₹44,000$.
