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

Answer:
200cm
Step-by-step explanation:
- by increasing the length of field by 50% the new length is = 60 + 60 × 50/100 = 60+30 =90m
- by decreasing the width of field by 50% the new width is = 20- 20×50/100 = 20 - 10 = 10m
- the new perimeter of rectangular farm = 2(l+b)= 2( 90 + 10) = 2×100 = 200m
