<h3><u>Answer;</u></h3>
To make the factory carbon neutral, the owners need to grow<em><u> 15000 trees</u></em> over an area of land measuring <em><u>75 acres</u></em>
<h3><u>Explanation and solution;</u></h3>
From the information;
900 kg CO2 = 1000 kg Cement
1 tree = 6 kg CO2
1 acre = 200 trees
<em>100000 kg Cement will require;</em>
<em>=(900 × 100000)/1000</em>
<em>= 90,000 kg of CO2</em>
<em>But 1 tree = 6 kg of CO2</em>
<em>Number of trees = 90,000/6</em>
<em> = 15,000 trees </em>
<em>But, 1 acre = 200 trees</em>
<em>Number of acres = 15,000/200</em>
<em> = 75 acres of land </em>
Therefore;
To make the factory carbon neutral, the owners need to grow<em><u> 15000 trees</u></em> over an area of land measuring <em><u>75 acres</u></em>
