3)14,4×10=144мм^2

Answer 2

Finding the Square Area

To find the square area, we need to know the length of one side of the square. In this case, the length of one side of the square is given as 1.2 dm (decimeters).

To calculate the square area, we use the formula:

Square Area = (Side Length)^2

Converting the side length from decimeters to centimeters and millimeters:

1 decimeter (dm) = 10 centimeters (cm) 1 centimeter (cm) = 10 millimeters (mm)

Therefore, the side length of the square is: - 1.2 dm = 1.2 * 10 cm = 12 cm - 1.2 dm = 1.2 * 10 * 10 mm = 120 mm

Now, let's calculate the square area:

Square Area = (12 cm)^2 = 144 cm^2 Square Area = (120 mm)^2 = 14,400 mm^2

So, the square area is 144 square centimeters (cm^2) and 14,400 square millimeters (mm^2).
