Let the length be 5a
Width = 3a
Cost= 9600
Rate = 24
Perimeter = Cost / Rate
2( 5x+3x) = 9600 / 24
=> 2 * 8x = 400
=> 16x = 400
=> x = 25
Length = 125
Width = 75
Width = 3a
Cost= 9600
Rate = 24
Perimeter = Cost / Rate
2( 5x+3x) = 9600 / 24
=> 2 * 8x = 400
=> 16x = 400
=> x = 25
Length = 125
Width = 75

Let length and breadth be 5x and 3x
Cost=Rs.9600
Rate=Rs.24
So,Perimeter=9600/24=400cm
ATQ
2 (L+B)=400cm
2 (5x+3x)=400cm
16x=400cm
x=400/16cm=25cm
So,Length=5x=5×25=125cm
And Breadth=3x=3×25=75cm
Cost=Rs.9600
Rate=Rs.24
So,Perimeter=9600/24=400cm
ATQ
2 (L+B)=400cm
2 (5x+3x)=400cm
16x=400cm
x=400/16cm=25cm
So,Length=5x=5×25=125cm
And Breadth=3x=3×25=75cm
