The area of rectangular plot is 440 m and its length is 22 m. Find itsperimeter.​

Answer»

Step-by-step EXPLANATION:

GIVEN:-

  • Area of rectangular plot is 440 m².
  • Length of rectangular plot is 22 m.

To find:-

  • Perimeter of rectangular plot.

Solution:-

  • Here, we are not having Breadth of rectangular plot for finding perimeter of rectangular plot. So, first we will find Breadth.

\boxed{\sf \bold{Area \: of \: rectangle = Length \times Breadth}}

PUT, length and area of rectangle in formula for finding breadth of plot.

\sf \longrightarrow 440 = 22 \times b

\sf \longrightarrow \dfrac{440}{22} = b

\sf \longrightarrow \purple{\boxed{\sf \bold{b = 20}}\star}

Breadth of rectangular plot is 20 m.

Now, According to question:

\boxed{\sf \bold{Perimeter\: of \: rectangle = 2(Length + Breadth)}}

Put, Length and Breadth of rectangular plot in formula :

\sf \longrightarrow 2 \times (22 + 20)

\sf \longrightarrow 44 + 40

\longrightarrow \red{\boxed{\sf \bold{84}} \bigstar}

Therefore,

Perimeter of rectangular plot is 84 m.
