Answer 2

Drawing a Square and Rectangle

To draw a square with sides measuring 4 cm, you would simply draw four equal-length sides that meet at right angles. Each side would measure 4 cm.

To draw a rectangle with sides measuring 4 cm and 2 cm, you would draw four sides, two of which are longer and measure 4 cm, and two of which are shorter and measure 2 cm. The longer sides would be parallel to each other, as would the shorter sides.

Here is a visual representation of the square and rectangle:

Square: ``` ---- | | | | ---- ```

Rectangle: ``` ------ | | | | ------ ```

Calculating the Perimeter of a Rectangle

To calculate the perimeter of a rectangle, you add up the lengths of all four sides. In this case, the rectangle has sides measuring 4 cm and 2 cm.

The formula for calculating the perimeter of a rectangle is: P = 2 * (a + b), where P is the perimeter, a is the length of one side, and b is the length of the adjacent side.

Using this formula, we can calculate the perimeter of the given rectangle as follows:

P = 2 * (4 + 2) = 2 * 6 = 12 cm

Therefore, the perimeter of the rectangle is 12 cm.
