Answer 2

Given :

• Are of the plot = 440 m²
• Length of the plot = 22 m

To Find :

• Breadth of the rectangle = ??
• Perimeter of the rectangle = ??

Formula To Be Applied :

We will use the formula of area and Perimeter of rectangle:

• Area = l×b
• or, Breadth = Area/Length

• Perimeter = 2(l+b)

Solution :

Given, Area = 440 m²

Length = 22 m

$\large\tt{ breadth = \frac{area}{length} }$

$\large\tt{ \implies b = \frac{440 \: {m}^{2} }{22m}}$

By cancelling, we get :

$\large \tt{ \implies b = \frac{ \cancel{440 \: {m}^{2} }}{ \cancel{22 \:m}}}$

$\red{ \underline{ \boxed{ \tt{ \implies b readth= 20 \: m}}}}$

Hence, we get that Breadth = 20 m

_____________________

So, we know the length and breadth:

$\tt{ \therefore perimeter = 2(l + b)}$

$\tt{ \implies p = 2(20 + 22)}$

$\implies \tt{p = 2(42)}$

$\green{ \underline{ \boxed{ \tt{ \therefore \: perimeter = 84 \: m}}}}$

Hence, Breadth = 84 cm
