Question

If the area of a rectangular plot is $240sq.m$ and its breadth is $12m$, then find the perimeter of the plot.

Answer 1

Step 1. Finding the length of the rectangular plot:

Lets us assume the length of the rectangular plot is $l$ and the breadth of the rectangular plot is $b$.

Given the breadth of the rectangular plot, $b=12m$

Given, the Area of the rectangular plot $=240sq.m$

We know, that the area of a rectangular plot $=$ $Length\times Breadth$

$=l\times b$

So, we got,

$l\times b=240$

$l\times 12=240$

$l=\frac{240}{12}=20m$

Therefore the length of the rectangular plot is $20m$.

Step 2. Finding the Perimeter of the rectangular plot:

Perimeter of rectangular plot $=2\left(l\times b\right)$

$=2\left(20+12\right)$

$=2\times 32$

$=64m$

Hence, the area of the rectangular plot is $64m$.
