• What are the dimensions of the triangle shown in the diagram?

  36 cm and 14 cm
• What are the dimensions of the rectangle shown in the diagram?

  30 cm and 4 cm
• How is the perimeter of the rectangle related to the perimeter of the triangle?

  The perimeter of the rectangle is a quarter of the perimeter of the triangle
• If the perimeter of the triangle is represented as \( P_t \), what is the formula for the perimeter of the rectangle \( P_r \)?

  P_r = \frac{1}{4} P_t
• How would you calculate the perimeter of the triangle with sides of 36 cm and 14 cm?

  By adding all the sides of the triangle
• What is the formula to calculate the perimeter of a rectangle?

  P = 2 \times (length + width)
• If the length of the rectangle is \( l \) and the width is \( w \), what is the perimeter of the rectangle in terms of \( l \) and \( w \)?

  P_r = 2(l + w)
• What is the total mark for Question 12?

  Total for Question 12 is 4 marks
• If the perimeter of the triangle is calculated to be \( P_t \), how would you find the length of the rectangle?

  By using the formula \( l = \frac{P_t}{8} \)
• What is the relationship between the perimeter of the triangle and the length of the rectangle?

  The length of the rectangle is derived from the perimeter of the triangle
