1. 2(l+b)=100m

   2(35+b)=100m

   70+2b=100

   2b=100-70

   2b=30

   b=30/2=15m

   Area of a rectangle =l×b

   35×15=525m^2

2. Answer:

   The area is 525m²

   Step-by-step explanation:

   let the breadth be ‘b’

   perimeter = 2(length+breadth)

   100 m = 2(35m + b)

   100 m = 70 m + 2b

   100m – 70 m = 2b

   30m = 2b

   30m/2= b

   15 m = b

   breadth = 15m

   Area = length×breadth

   Area = 35m×15m

   Area= 525 m²
