Answer:
The length of a side of the original square is 6 meters long.
Step-by-step explanation:
First, you need to know that finding the area of a square means multiplying two sides together. You also need to know that a square has four equal sides, meaning that the area is a square of a number. This means that since the area of the new square is 64 square meters, then finding a side length would mean finding the square root of 64. Using a calculator, you see that the square root of 64 is eight. This means that the second square has a side length of 8 meters.
Next, the problem tells you the sides of the new square were increased by 2 meters. All you would have to do is subtract 8 by two, which equals six. That being said, the length of a side of the original square would be six meters.
+The area of the original square would be 36 meters, because 6 times 6 (side times side) equals 36.
