let the length and breadth be 5x and 3x.
perimeter=600
p=2 (l+b)
600=2 (5x+3x)
600=2 (8x)
16x=600
x=600/16
x=37.5
length =5x=5 (37.5)=187.5
breadth=3x=3 (37.5)=112.5
perimeter=600
p=2 (l+b)
600=2 (5x+3x)
600=2 (8x)
16x=600
x=600/16
x=37.5
length =5x=5 (37.5)=187.5
breadth=3x=3 (37.5)=112.5

let the length =5x
and breadth = 3x
if perimeter is 600
then
perimeter = 2(l+b)
here, 600 = 2(5x+3x)
600/2 =8x
300 = 8x
300/8 =x
then lenght = (5*300/8) = 1500/8 = 187.5
breadth = (3*300/8) = 900/8 =112.5
and breadth = 3x
if perimeter is 600
then
perimeter = 2(l+b)
here, 600 = 2(5x+3x)
600/2 =8x
300 = 8x
300/8 =x
then lenght = (5*300/8) = 1500/8 = 187.5
breadth = (3*300/8) = 900/8 =112.5
