If a park covers 3500 square metres and planners want 25 trees per 100 square metres, how many trees are needed?

Step-by-step solution

1. Step 1: Calculate number of 100‑square‑metre units in 3500 m²: $3500÷100=35$ units.
2. Step 2: Multiply by desired trees per unit: $35\times 25=875$ trees.
3. Step 3: State the total number of trees required = 875.
