Question

The area of a rectangular ground is $120m^2$ and its length is $12$ m. Find the cost of fencing the ground at the rate of $Rs.125$ per metre.

Answer 1

We have, Area of the rectangular ground $=120m^2$ and

Length of the ground $=12m$

Now, Breadth of the ground=Area of the ground

Length of the ground $=\frac{120}{12}=10m$

Also, Perimeter of the ground $=2\times$ (Length $+$ Breadth)

$=2\times (12+10)$

$=2\times 22=44m$

Since, the rate of fencing the ground $=Rs.125$ per metre

So, the cost of fencing the ground $=125\times 44=₹5500$
