Question

Find the breadth of a rectangular plot of land, if its area is 440 m2 and the length is 22 m. Also find its perimeter. ​

Answer 1

Given :

• Area of Rectangular Plot is 440 m² .
• Length of plot is 22 m .

To Find :

• Breadth and Perimeter of Rectangular plot .

Solution :

$\longmapsto\tt{Length=22\:m}$

Using Formula :

$\longmapsto\tt\boxed{Area\:of\:Rectangle=l\times{b}}$

Putting Values :

$\longmapsto\tt{440=22\times{b}}$

$\longmapsto\tt{\cancel\dfrac{440}{22}=b}$

$\longmapsto\tt\bf{20\:m=b}$

So , The Breadth of plot is 20 m .

Now ,

$\longmapsto\tt{Length=22\:m}$

$\longmapsto\tt{Breadth=20\:m}$

Using Formula :

$\longmapsto\tt\boxed{Perimeter\:of\:Rectangle=2(l+b)}$

Putting Values :

$\longmapsto\tt{2(22+20)}$

$\longmapsto\tt{2(42)}$

$\longmapsto\tt\bf{84\:m}$

So , The Perimeter of plot is 84 m .

_______________________

• Area of Rectangle = l × b
• Perimeter of Rectangle = 2(l+b)
• Diagonal of Rectangle = √(l)² + (b)²
• Area of Square = Side × Side
• Perimeter of Square = 4 × Side
• Diagonal of Square = √2a (here a = side)

Answer 2

$\huge\sf\underline\purple{Solution}$

Given,

Length of rectangle is 22m

Breadth of rectangle is y (we have to find)

Area of rectangle =440m²

FORMULA:-

AREA OF RECTANGLE = LENGTH × BREADTH

So,

400m² = 22m × y

y = $\frac{440m²}{22m}$

y=20m

So,breadth of rectangle is 20m

Perimeter =?

FORMULA:-

PERIMETER OF RECATANGLE = 2(l + b)

So, Already we know length and breadth

Perimeter = 2(22m +20m)

Perimeter = 2(42m)

Peeimeter = 84m

So, Final required answers are

Breadth of rectangle = 20m

Perimeter of rectangle = 84m
