Final answer:
The area of a square piece of plywood with each side measuring 5 feet is 25 square feet, found by multiplying the length of one side by itself.
Step-by-step explanation:
To calculate the area of a square piece of plywood where each side is 5 feet long, you use the formula Area = side × side. Since all sides of a square are equal, we can simply multiply 5 feet by 5 feet to get the area. So, the calculation will be:
Area = 5 feet × 5 feet = 25 square feet.
This means the area of the square piece of plywood is 25 square feet.
