Question

the length of the rectangular plot of land is twice its breadth if the perimeter of the plot be 180 meters then find its area​

Answer 1

 Units are ignored in calculation.

Answer:

1800 m^2

Step-by-step explanation:

 Let the breadth of the rectangle be a

         As length is twice of breadth, it should be 2a.

Given,

⇒ Perimeter = 180

   Perimeter of rectangle = 2( length + breadth )

⇒ 2( 2a + a ) = 180

⇒ 2( 3a ) = 180

⇒ 6a = 180

⇒ a = 30

   Area of rectangle = length * breadth

⇒ Area of rectangle = 2a * a

                = 2a^2

                = 2( 30 )^2

                = 2( 900 )

                = 1800

Answer 2

Answer: 4050

Step-by-step explanation:

Perimeter = 180, than length will be 90, and breadth will become 45.

90 multiplied by 45 will give you 4050.

Hope this helps!
