1.	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» 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

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»

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
