Here's how to find the length of one side:

* **Perimeter of a square:** The perimeter is the total length of all its sides added together.
* **Square sides:** All sides of a square are equal in length.

Let's represent the length of one side of the square with the variable 's'.

* **Formula:** Perimeter = 4s (since there are 4 equal sides)

We know the perimeter is 12 meters:

* 12 = 4s

To find the length of one side ('s'), we need to solve for 's':

* 12 / 4 = s
* 3 = s

### Answer: 3 meters 

Expected answer: 3

Correct? Yes

Problem: A quadrilateral has a perimeter of 160m. If the three known sides have lengths of 29m, 16m, and 41m, what is the length of the fourth side?

Gemini-1.5 Flash:

Reasoning: The perimeter of a quadrilateral is the sum of the lengths of its four sides.  We know the lengths of three sides, so we can subtract their sum from the total perimeter to find the length of the fourth side. 

The sum of the three known sides is 29m + 16m + 41m = 86m.

Subtracting this sum from the total perimeter gives us 160m - 86m = 74m.

### Answer: 74m 

Expected answer: 74

Correct? Yes

Problem: A rectangle has a perimeter of 98m. If one of its sides is 5m long, what is the length of the other side?

Gemini-1.5 Flash:

Here's how to solve the problem:

* **Perimeter Formula:** The perimeter of a rectangle is found by adding up the lengths of all its sides: Perimeter = 2 * (length + width).
* **We know:** 
    * Perimeter = 98m
    * One side (let's call it the width) = 5m
* **Let's find the length:**
    * 98 = 2 * (length + 5)
    * 98 = 2 * length + 10
    * 98 - 10 = 2 * length
    * 88 = 2 * length
    * length = 88 / 2
    * length = 44m

### Answer: 44m 

Expected answer: 44

Correct? Yes

Problem: A rectangle has two sides measuring 45m each. If the total perimeter of the rectangle is 210m, what is the length of each of the other two sides?

Gemini-1.5 Flash:

Here's how to solve the problem:

1. **Perimeter and Sides:** The perimeter of a rectangle is the total length of all its sides.  We know the perimeter is 210m.

2. **Known Sides:** We know two sides are 45m each, totaling 45m * 2 = 90m.

3. **Remaining Sides:**  Subtract the known sides from the total perimeter to find the length of the remaining two sides: 210m - 90m = 120m.

4. **Equal Sides:** Since the remaining sides are equal, each side is 120m / 2 = 60m.

### Answer: 60m 

Expected answer: 60

Correct? Yes
