Answer: The measure (x+24)(x-10) represents the AREA of the rectangular school gym.
Step-by-step explanation: Given that a rectangular school gym has a length of (x+24) and a width of (x-10).
We are to find the measure that (x+24)(x-10) represent.
The expression (x+24)(x-10) is the product of the length and breadth of the given rectangular school gym.
Also, we know that
the product of the length and breadth of any rectangle is equal to the area of that rectangle.
Therefore, the measure (x+24)(x-10) represents the AREA of the rectangular school gym.
