Let,

The length of rectangle = x unit

And breadth of the rectangle = y unit

Now, as per the question given,

(x â€“ 5) (y + 3) = xy -9

3x â€“ 5y â€“ 6 = 0â€¦â€¦â€¦â€¦â€¦â€¦â€¦â€¦â€¦â€¦â€¦(1)

(x + 3) (y + 2) = xy + 67

2x + 3y â€“ 61 = 0â€¦â€¦â€¦â€¦â€¦â€¦â€¦â€¦â€¦â€¦..(2)

Using cross multiplication method, we get,

x/(305 +18) = y/(-12+183) = 1/(9+10)

x/323 = y/171 = 1/19

Therefore, x = 17 and y = 9.

Hence, the length of rectangle = 17 units

And the breadth of the rectangle = 9 units
