Dave has a house with a huge rectangular garden inside it. One day, Dave makes the following observations: - If the garden’s length was 5 m less and its breadth was 2 m more, the garden’s area would have been 80 m² less than the actual area.
- If the garden’s length was 10 m more and its breadth was 5 m less, the garden’s area would have been 50 m² more than the actual area.

What are the actual dimensions of the garden?
