MARK ME BRAINLIEST......

Step-by-step explanation:

Let Breadth of rectangle be X cm.

Length of rectangle = 2X cm.

Perimeter of rectangle = 60 cm

2 ( L + B ) = 60 cm

2 ( 2X + X ) = 60 cm

3X = 30

X = 30/3

X = 10 cm.

Breadth of rectangle = X = 10 cm.

And,

Length of rectangle = 2X = 2 × 10 = 20 cm.
