Diện tích bác Hà làm lối đi và trồng hoa chiếm số phần trăm là:

\(100\%-47\%-35\%=18\%\) (diện tích mảnh đất)

Diện tích mảnh đất đó là:

\(56\times48=2688\) (m²)

Diện tích bác Hà làm lối đi và trồng hoa là:

\(\dfrac{2688}{100}\times18\%=483,84\) (m²)

                    Đáp số: \(483,84\) m²

\(0,75\times x-0,2\times x=2,75\\ \Rightarrow\left(0,75-0,2\right)\times x=2,75\\ \Rightarrow0,55\times x=2,75\\ \Rightarrow x=2,75\div0,55\\ \Rightarrow x=5\)
