Which of these could measure 25 cm in length? Explain why you think this.

The objects are a toy mouse, a mat/rug, and a broom.

• A toy mouse is usually very small, around $5 \text{ cm}$ to $10 \text{ cm}$ long.
• A mat or small rug can vary in size, but a length of $25 \text{ cm}$ is a reasonable size for a small mat (e.g., a bath mat or a small doormat).
• A broom is typically much longer, usually around $100 \text{ cm}$ to $150 \text{ cm}$ (or $1 \text{ m}$ to $1.5 \text{ m}$) in length.

$25 \text{ cm}$ is roughly the length of a standard school ruler (which is $30 \text{ cm}$) or the width of a piece of A4 paper.

The toy mouse is too short, and the broom is too long. A small mat or rug is the most appropriate object that could measure approximately $25 \text{ cm}$ in length.

The object that could measure $25 \text{ cm}$ in length is the mat/rug.
This is because $25 \text{ cm}$ is a common length for a small mat, while a toy mouse is typically much shorter and a broom is much longer.
