A square is of side 4dm, find its area in cm square.
4 dm = 40 cm
so area = 40^2 or 1600 cm^2
To find the area of a square, you multiply the length of one of its sides by itself.
Given that the side of the square is 4 dm, we can convert it to centimeters (cm) using the conversion factor: 1 dm = 10 cm.
So, the length of one side in centimeters is: 4 dm × 10 cm/dm = 40 cm.
To find the area, we calculate: area = side × side = 40 cm × 40 cm = 1600 cm^2.
Therefore, the area of the square is 1600 square centimeters (cm^2).
To find the area of a square, you need to multiply the length of one of its sides by itself. Let's convert 4 dm to centimeters (cm) since the area should be in square centimeters (cm^2).
1 decimeter (dm) is equal to 10 centimeters (cm), so multiplying 4 dm by 10 cm/dm gives us:
4 dm * 10 cm/dm = 40 cm
So, the side length of the square is 40 cm. Now let's find the area:
Area = side length * side length
Area = 40 cm * 40 cm
Area = 1600 cm^2
Therefore, the area of the square with a side length of 4 dm is 1600 cm^2.
