What could be the possible lengths of the missing sides if the total perimeter is 18 cm?

Explanation:
To determine the possible lengths of the missing sides given a total perimeter of 18 cm, we first need to understand what perimeter represents. The perimeter of a shape, particularly a polygon like a triangle or rectangle, is the sum of the lengths of all its sides. If we know that the total perimeter is 18 cm and we have two missing sides, we can set up an equation. Let's call the lengths of the two missing sides 'x' and 'y'. According to the perimeter rule, we have: x + y = 18 cm. From this equation, we can analyze the choices given. For the option that is selected, the lengths 6 cm and 7 cm satisfy the equation because: 6 cm + 7 cm = 13 cm. However, since this does not add up to 18 cm, this answer choice cannot represent the missing sides based on the perimeter rule, so this needs to be reevaluated. If we check the other options: If we take the option of 5 cm and 6 cm, this measures out to 11 cm, which again does not meet the requirement. Looking at the option of 4 cm and 9 cm, this gives us a total of 13
