The garden is 50m wide and twice as long as wide. How many trees can be planted on this area if 10m2 is allocated for 1 tree.

Let’s find the length of the garden, for this we multiply the width by two:
1) 50 * 2 = 100 (m) – the length of the garden.
Since the garden has the shape of a rectangle, in order to find its total area, we use the formula: S = a * b, where a is the width, b is the length of the garden:
2) 50 * 100 = 5000 (m2) – the total area of the garden.
In order to find out how many trees can be planted on this site, the total area must be divided by the area calculated for one tree:
3) 5000: 10 = 500 (d).
Answer: 500 trees can be planted in this area.
