Answer 3

Perimeter of a Rectangle

To find the perimeter of a rectangle, you need to add up the lengths of all its sides. The formula for the perimeter of a rectangle is:

Perimeter = 2 * (length + width)

Let's calculate the perimeter of a rectangle with sides measuring 3 dm and 5 dm.

Given: Length = 3 dm Width = 5 dm

Using the formula, we can calculate the perimeter as follows:

Perimeter = 2 * (3 dm + 5 dm) Perimeter = 2 * 8 dm Perimeter = 16 dm

Therefore, the perimeter of the rectangle is 16 dm.

Perimeter of a Square

To find the perimeter of a square, you need to add up the lengths of all its sides. Since a square has all sides equal, you can simply multiply the length of one side by 4. The formula for the perimeter of a square is:

Perimeter = 4 * side

Let's calculate the perimeter of a square with a side length of 5 dm.

Given: Side = 5 dm

Using the formula, we can calculate the perimeter as follows:

Perimeter = 4 * 5 dm Perimeter = 20 dm

Therefore, the perimeter of the square is 20 dm.

To summarize: - The perimeter of the rectangle with sides measuring 3 dm and 5 dm is 16 dm. - The perimeter of the square with a side length of 5 dm is 20 dm.

Please note that the calculations are based on the given measurements and formulas.
