Question

find a breadth of a rectangular plot of land , if it's area is 440m2 and the length is 22m.also find perimeter.

Answer 1

Answer :

$\bold{Breadth \: = \: 20 \: metres}$

$\bold{Perimeter \: = \: 84 \: metres}$


Explanation :

Given :

Area = 440 m^2

length = 22 m


Finding the breadth :-

Area of a Rectangle = length x breadth

Area = 22 m x breadth

440 = 22 x breadth

breadth = 440/22

breadth = 20 metres


Finding the Perimeter :-

Length = L

Breadth = B

Perimeter of a Rectangle = 2(L + B)

Perimeter = 2(22 + 20)

Perimeter = 2(42)

Perimeter = 84 meters.


Hence :

Breadth = 20 metres

Perimeter = 84 metres

Answer 2

$\textsf{\large{Answer :}}$

$\textsf{\large{Breadth = 20 meter}}$
$\textsf{\large{Perimeter = 84 meter}}$

$\textsf{\large{Explaination :}}$

$\textsf{\large{Given :}}$

• Length of the rectangular field = 22m
• Area of the rectangular field = 440m²

★ $\textsf{\large{To find :}}$

→ Breadth and Perimeter of the rectangular field.

★ $\textsf{\large{Solution :}}$

• Consider the length as $\textsf{x}$

• $\textbf{Area of rectangle = }$

$\mathbf{Length \times breadth}$

→ $\mathbf{440 = 22 \times x}$

→ $\mathbf{440 = 22x}$

→ $x = \mathbf{\frac{440}{22}}$

→ $\mathbf \: x = 20$

$\large{\green{\boxed{\green{\boxed{\red{\textsf{L \: = \: 20}}}}}}}$


→ $\textsf{\large{Perimeter of Rectangle}}$

→ $\mathbf{2(L + B)}$

→ $\mathbf{2(20+22)}$

→ $\mathbf{40 + 44}$

→ $\mathbf{84 m}$

$\large{\green{\boxed{\green{\boxed{\red{\textsf{Perimeter = 84 m }}}}}}}$

$\therefore$The Breadth of the rectangular field is 20m

$\therefore$ The Perimeter of the rectangular field is 84m
