Answer:
Length = 16m
Width = 12 m
Step-by-step explanation:
The length and width of the plot are in the ratio 4:3.
Let say length = 4L
Width = 3L
Perimeter = 2 (4L + 3L) = 2 * 7L = 14L m
The fence costs ₹ 30 per meter.
Total Cost = 14L * 30 = 420 L
420L = 1680
=> L = 4
Length = 4L = 16 m
Width = 3L = 12 m
