Question

the length of a rectangular plot of land is twice its breadth if the perimeter of the floor is 180m then find its area

Answer 1

Area of rectangular pilot l*b
L. = x
B= x
Area l*b
X*x =2x= 180
X=180/2=90. Ans....
Plz mark me as brainliest

Answer 2

Let the breadth of plot be x

Therefore length = 2x

Perimeter = 180 m

We know that,

Perimeter of rectangle = 2 ( l + b )

180 = 2 ( x + 2x )

➡ 2 ( 3x ) = 180

➡ 6x = 180

➡ x = 180/6 = 30m

Length of rectangular plot = 2x = 2(30) = 60 m

Breadth of plot = x = 30 m

Area of rectangle = l × b

➡ 30 × 60

➡ 1800 m²

Answer :-

Area of rectangular plot will be 1800 m².
