Martin wants to draw a square which has a perimeter of 49 cm. How long does each side need to be?

1. Break Down the Problem

To find the length of each side of a square given its perimeter, we need to understand that a square has four equal sides. Therefore, we can express the relationship between the perimeter and the side length mathematically.

2. Relevant Concepts

The formula for the perimeter $P$ of a square is given by: $P = 4s$ where $s$ is the length of one side of the square.

3. Analysis and Detail

Given that the perimeter $P$ is 49 cm, we can set up the equation: $4s = 49$ To find the side length $s$, we can isolate $s$: $s = \frac{P}{4}$

4. Verify and Summarize

Now, substituting the values: $s = \frac{49}{4} = 12.25 \, \text{cm}$

The calculations are correct.

Final Answer

Each side of the square needs to be $12.25 \, \text{cm}$ long.
