The area of a rectangle is given by the formula:
Area = length x width
In this case, the length of the park is x + 5 and the width is x - 2. So, we can substitute these expressions into the formula to get:
Area = (x + 5) x (x - 2)
Expanding the product, we get:
Area = x^2 + 5x - 2x - 10
Simplifying, we have:
Area = x^2 + 3x - 10
Therefore, the area of the rectangular park is given by the expression x^2 + 3x - 10.
