Answer 2

Finding the Area of the Original Square

To find the area of the original square, we can use the formula for the area of a square, which is given by the formula: Area = side length * side length.

Given that the area of the new square is 196 cm^2 and the side length of the new square is 4 cm, we can calculate the area of the original square using the following steps:

1. Calculate the Area of the Original Square: - Area = side length * side length - Area = 4 cm * 4 cm - Area = 16 cm^2

So, the area of the original square is 16 cm^2.

This calculation is based on the formula for the area of a square and the given dimensions of the new square.
