Answer: 102
Explanation:
The forest covers 51,000 acres. The survey found that 0.2% of the forest is old-growth trees. To find the number of acres of old-growth trees, we can multiply the total area of the forest by the percentage of old-growth trees:
Old-growth trees=Total area of forest×Percentage of old-growth trees
Substituting the values, we get:
Old-growth trees=51,000 acres×0.2%=102 acres
Therefore, there are 102 acres of old-growth trees in the forest
