Question

12 changing the dimensions of a quadrilateral does not affect the perimeter of the shape true false

Explanation:

To determine if changing the dimensions of a quadrilateral affects its perimeter, we recall that the perimeter of a quadrilateral is the sum of its side lengths (e.g., for a rectangle, \( P = 2(l + w) \), where \( l \) is length and \( w \) is width). If we change \( l \) or \( w \), the perimeter changes. For example, a rectangle with \( l = 2 \), \( w = 3 \) has \( P = 2(2 + 3)=10 \). If we change \( l \) to 4, the new perimeter is \( 2(4 + 3)=14 \), which is different. So changing dimensions (side lengths) of a quadrilateral does affect its perimeter, making the statement false.

Answer:

False
