Let the length be 4a
Width = 3a
Area = 1728
=> 3a *4a = 1728
=> 12a^2 = 1728
=> a^2 = 144
=> a = 12
Length = 48 m
Width = 36 m
Perimeter = 2(48 + 36)
= 2* 84
= 168 m
Width = 3a
Area = 1728
=> 3a *4a = 1728
=> 12a^2 = 1728
=> a^2 = 144
=> a = 12
Length = 48 m
Width = 36 m
Perimeter = 2(48 + 36)
= 2* 84
= 168 m

Let the ratio be 4x and 3x
4x*3x=1728
12x²=1728
X²=144
X=12
4*12=48
3*12=36
I hope answer is correct
4x*3x=1728
12x²=1728
X²=144
X=12
4*12=48
3*12=36
