1. Step-by-step explanation:

   Answer:

   breadth = 10 m

   Perimeter = 100 metres

   Explanation:

   Let the breadth be b metre

   Area of rectangle = 400 m²

   Length of rectangle ,l = 40 m

   Now, we know that area of rectangle is the product of length and breadth . So,

   • Area of rectangle = length × breadth

   → 400 = 40 × b

   → 400/40 = b

   → 10 = b

   → b = 10 m

   Hence, the breadth of the rectangle is 10 metres

   Now, calculating the perimeter of the rectangle

   • Perimeter of rectangle = 2 (length+breadth)

   → Perimeter of rectangle = 2 (40+10)

   → Perimeter of rectangle = 2×50

   → Perimeter of rectangle = 100 m

   Hence, the perimeter of the rectangle is 100 metres.
