Answer: Length = 43 ; Breadth = 21.5

Step-by-step explanation:

Let the width be 'x'

The length = 2x

The perimeter = 129

Formula of perimeter of rectangle = 2 ( length + breadth )

Substitute:

2 ( 2x + x ) = 129

2 ( 3x ) = 129

6x = 129

x = 21.5

Therefore, the width = 21.5

Length = 2x = 2(21.5) = 43
