1. Answer:

   200cm

   Step-by-step explanation:

   1. by increasing the length of field by 50% the new length is = 60 + 60 × 50/100 = 60+30 =90m
   2. by decreasing the width of field by 50% the new width is = 20- 20×50/100 = 20 – 10 = 10m
   3. the new perimeter of rectangular farm = 2(l+b)= 2( 90 + 10) = 2×100 = 200m

2. 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
