Answer 2

Given,

Area of space $\[ = 0.50k{m^2}\]$

Area for 1 tree $\[ = 4m \times 2.5m\]$

Solution,

Total area of space,

$\[\begin{array}{l} = 0.50k{m^2}\\ = 0.50 \times {\left( {1000m} \right)^2}\\ = 0.50 \times {10^6}{m^2}\\ = 5 \times {10^5}{m^2}\end{array}\]$

Area required for 1 tree,

$\[ = 4m \times 2.5m\]$

Calculate the total number of trees,

$\[ = \frac{{5 \times {{10}^5}{m^2}}}{{4 \times 2.5{m^2}}}\]$

$\[ = \frac{{5 \times {{10}^5}}}{{10}}\]$

$\[ = 50000\]$

Hence the number of trees are $\[50000\]$.
