Final answer:
To determine the size of the expanded skate park, we add x yards to the original dimensions and then calculate the area using the formula for the area of a rectangle (length × width).
Step-by-step explanation:
The student's question pertains to the expansion of a rectangular skate park. To find the new dimensions and area, one would add x yards— a variable representing the increase in size— to both the length and the width of the original rectangle. To calculate the area of the expanded skate park, one would use the formula for the area of a rectangle: Area = length × width. Assuming that x yards are added to both dimensions, the new length becomes 60 + x yards, and the new width becomes 50 + x yards. The area of the expanded rectangle would then be (60 + x) × (50 + x) square yards.
