Answer:
For a, the machine depreciates 20% of its current value each year. So, It will lose 20% of its value in the first year. Then in the second year, it will lose 20% of THAT value (not of the original value) and so on.
b) Since the machine loses 20% of its value each year, it retains 80% of its value each
Answer:
Since,
Length is 4 times Breadth
Let Breadth be x
Therefore,Length=4x
Perimeter=50m
Therefore,
50m=2(l+b)
50m=2(4x+x)
50m=2(5x)
50m=10x
x=5m.
Therefore,
Breadth=5m
Length=4x=4×5=20m
