Answer 2

Drawing a Rectangle

To draw a rectangle with sides measuring 4 cm and 5 cm, follow these steps:

1. Start by drawing a straight line segment of length 4 cm. 2. From one end of the line segment, draw a perpendicular line segment of length 5 cm. 3. Connect the other ends of the two line segments to form a rectangle.

Here is a visual representation of the rectangle:

   _______
  |       |
  |       |
  |_______|

Calculating the Area and Perimeter

To calculate the area and perimeter of the rectangle, we can use the following formulas:

- Area of a rectangle: A = length × width - Perimeter of a rectangle: P = 2 × (length + width)

In this case, the length of the rectangle is 4 cm and the width is 5 cm.

1. Area: - Using the formula, we can calculate the area as follows: - A = 4 cm × 5 cm = 20 cm².

2. Perimeter: - Using the formula, we can calculate the perimeter as follows: - P = 2 × (4 cm + 5 cm) = 2 × 9 cm = 18 cm.

Therefore, the area of the rectangle is 20 cm² and the perimeter is 18 cm.
