Question

The length of a rectangular plot is twice its breadth.If the perimeter of the plot be

1200m,find its area
​

Answer 1

Answer:

Answer:

Area of the rectangular plot = 2592 m²

Step-by-step explanation:

Given :

Perimeter of the plot = 216 m

Length is twice its Breadth

To find: The area of the rectangular plot

Concept : First find the length and Breadth of the rectangular plot . After that find the area of the plot .

Let the length be 2x

Let the Breadth be x

So , to find the length and breadth use this equation -:

After finding the Breadth multiply it with 2 to find the length.

After that to find the area of the rectangular plot use this formula -:

Where,

A = Area

L = Length

B = Breadth

Solution :

Length -:

Area of the rectangular plot -:

So , the area of the rectangular plot is 2592m² ...

ᴛʜᴇ ʟᴇɴɢᴛʜ ᴏꜰ ʀᴇᴄᴛᴀɴɢʟᴇ ᴘʟᴏᴛ ɪꜱ ᴛᴡɪᴄᴇ ɪᴛꜱ ʙʀᴇᴀᴅᴛʜ.

ꜱᴏʟᴜᴛɪᴏɴ:-

ʟᴇɴɢᴛʜ ɪꜱ ᴛᴡɪᴄᴇ ɪᴛꜱ ʙʀᴇᴀᴅᴛʜ ᴛʜᴇɴ ʟᴇɴɢᴛʜ ɪꜱ " 2x "

⟹ᴘᴇʀɪᴍᴇᴛᴇʀ=2(ʟ+ʙ)

⟹1200=2(2x+x)

⟹1200=2(3x)

⟹1200=6x

$\tt\implies \: x = \cancel\dfrac { 1200 } { 6 }$

⟹x=200
