Answer:
The area of the park is 2.45 acres
Explanation:
In order to get a number exactly between other two numbers, you have to add them and then divide that result by two. In a mathematical expression: (a + b)/2, where a and b are those two numbers. In this case, the exactly between 2.4 and 2.5 acres is (2.4 + 2.5)/2 = 2.45 acres.
