Length of Rectangle = 2 × Breadth

  • Let Breadth = x

⇒ Length of Rectangle = 2x

  • We know :

⇒ Area of Rectangle = Length × Breadth

⇒ 320 = 2x × x

⇒ 320 = 2x²

⇒ 320/2 = x²

⇒ 160 = x²

⇒ 12.64 = x

  • Length of Rectangle = 2x = 2 × 12.64 = 25.28
  • Breadth of Rectangle = x = 12.64

लंबाई = 2a

चौड़ाई = a

क्षेत्रफल = L x B

320 = 2a x a

320/2 = a²

160 = a²

4√10 = a = चौड़ाई

2a = 2x4√10 = 8√10 = लंबाई

परिमित ई = 2(l+b)

= 2 (8√10 + 4√10)

= 2 (12√10)

24√10
