RECTANGULAR PLOT :-
Let its breadth be X metre.
Then, its length = (3X/2) metre.
Area = length × breadth
Or, 2400 = (3X/2) × X
Or, 2400 = 3X²/2
Or, X = 40
So, breadth = 40 metre.
Length = (3×40/2) or 60 metre.
Considering the length be "l" and breadth be "b" metres respectively, we can say :
Perimeter = 2(l+b)
Or, Perimeter = 2 (60+40) metre.
Or, Perimeter = 200 metre.

Hello
Area of rectangular plot = 2400 m²
Let breadth , b = x
LENGTH is 1 1/2 times than breadth means :
3/2 times bigger
So, length , l=( 3/2 ) x
Area of rectangle = 2400
l * b = 2400
x * (3/2) x = 2400
3x² / 2 = 2400
x² = 2400 * 2/3
x = √1600
x = 40
So, breadth = 40 m
length = 3/2 * 40
length = 60
Perimeter of rectangle = 2(l + b)
= 2 ( 40 + 60 )
= 2 * 100
= 200 m
