Given:

Width = x

Length = 2 × Width = 2x

Perimeter of a rectangle = 2(Length + Width)

Explanation

Let's call the marked price "x".

Since Saba got a 30% discount, she paid 70% of the marked price (100% - 30% = 70%).

The amount she paid is Rs. 6300, so:

70% of x = 6300

0.7x = 6300

x = 6300 / 0.7

x = 9000
