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
