Draw a rectangle and label its dimensions (length = 10 cm, width = 4 cm). Calculate its perimeter and area. (5 marks)

1 answer

I can't draw directly, but I can guide you on how to visualize and calculate the dimensions of a rectangle with the specified attributes.

  1. Drawing the Rectangle:

    • Draw a rectangle.
    • Label one side as the length (10 cm) and the adjacent side as the width (4 cm).
  2. Calculating the Perimeter: The formula for the perimeter \( P \) of a rectangle is: \[ P = 2 \times (\text{length} + \text{width}) \] Substituting the given values: \[ P = 2 \times (10 , \text{cm} + 4 , \text{cm}) = 2 \times 14 , \text{cm} = 28 , \text{cm} \]

  3. Calculating the Area: The formula for the area \( A \) of a rectangle is: \[ A = \text{length} \times \text{width} \] Substituting the given values: \[ A = 10 , \text{cm} \times 4 , \text{cm} = 40 , \text{cm}^2 \]

Summary of Calculations:

  • Perimeter: \( 28 , \text{cm} \)
  • Area: \( 40 , \text{cm}^2 \)

Feel free to draw the rectangle and use these calculations for reference!
