Question

Find the breadth of a rectangle plot of land if its area is 440 square metre and the length is 22 also find its perimeter

Answer 1

Given

$\bold{Area \ of \ the \ rectangular \ plot} = 440 \ m^{2}$

$\bold{Length \ of \ the \ rectangular \ plot} = 22 \ m$

SOMETHING YOU NEED TO KNOW

Area of the rectangle = Length * Breadth

Perimeter of the rectangle = 2(Length + Breadth)

Let the width of the rectangular plot be x.

$\implies 22x=440$

$\implies x = \dfrac{440}{22}$

$\implies x = 20 \ m$

$\boxed{\boxed{\bold{Therefore, \ the \ breadth \ of \ the \ rectangular \ plot \ is \ 20 \ m}}}}}}}}}}$

Perimeter

$= 2(22+20)\\= 2(42)\\= 84 \ m$

$\boxed{\boxed{\bold{Therefore, \ the \ perimeter \ of \ the \ rectangular \ plot \ is \ 84 \ m}}}}}}}}}}$

                                                           

Answer 2

Answer:

Breadth is 20 m and Perimeter is 84 m.

Step-by-step explanation:

Given,

length( len ) = 22 m and area = 440 sq m.

let, breadth be $x^{}$ m

area of rectangle = length × Breadth

⇒ 440 = len × $x^{}$

⇒  440 = 22 × $x^{}$

⇒ $x^{}$ = 440 ÷ 22

∴  $x^{}$ = 20

So, breadth = 20 m

Now,

   perimeter of rectangle = 2 (length  breadth )

            = 2 ( 22 + 20  ) m

            = 84 m

∴ The perimeter of the rectangle is 84 m.
