Let ratio be x= 7x and 3x
Perimeter of rectangle = 2 (l+b)
30m = 2 (7x +3x)
30m/2 = (10x)
15m = 10x
15m/10 = x
1.5m = x
Hence, 7x = 7×1.5m = 10.5m
3x = 3×1.5m = 4.5m
Perimeter of rectangle = 2 (l+b)
30m = 2 (7x +3x)
30m/2 = (10x)
15m = 10x
15m/10 = x
1.5m = x
Hence, 7x = 7×1.5m = 10.5m
3x = 3×1.5m = 4.5m
