Q. 3.     Find the breadth of a rectangular plot of land, if its area is $440\; m^{2}$ and the length is $22\; m$. Also find its perimeter.

It is given that the area of rectangular land is $440\; m^{2}$ and the length is $22\; m$

Now, we know that

Area of rectangle is $= length \times breath$

$\Rightarrow 440 = 22 \times breath$

$\Rightarrow breath = \frac{440}{22} = 20 \ m$

Now,

The perimeter of the rectangle is $=2(l+b)$

$\Rightarrow 2(l+b) = 2(20+22)=2\times 44 = 88 \ m$

Therefore, breath and perimeter of the rectangle are 20m and 88m respectively
