Answer:
200 m
Step-by-step explanation:
Original length = 60 m
breadth = 20 m
New length = original + 50% of original
= 60 + 50% of 60
= 60 + (50/100 × 60)
= 90 m
New breadth = original - 50% of original
= 20 - 50% of 20
= 20 - (50/100 × 20)
= 10 m
New perimeter = 2(length + breadth)
= 2(90 + 10)
= 200 m
