Question

A rectangular plot of land is $240m$ by $200m$. The cost of fencing per meter is $Rs30$. What is the cost of fencing the entire field?

Answer 1

We have sides of rectangular plot of land is $240m$ and$200m.$

Length of fence = Perimeter of the rectangular plot

That is, Perimeter of the rectangular plot =$2(l+b)$

Perimeter of the rectangular plot =$2(240+200)$

Perimeter of the rectangular plot= $2\times 440$

i.e Perimeter of the rectangular plot = $880m$

Now we have, cost of fencing 1 meter =$30Rs$

cost of fencing 880 meter =$30\times 880=26400Rs$

Thus fencing cost of entire field will be$26400Rs.$
