To find the area of a square, simply multiply the side length by itself.  As \(\displaystyle 11.8\) is the side length, that's the number you will multiply by itself.  The best answer is:

\(\displaystyle 11.8 * 11.8 = 139.24\)

To find the area of a square, simply multiply the side length by itself. As \(\displaystyle 4.1\) is the side length, that is the number you will use. The best answer is:

\(\displaystyle 4.1 * 4.1 = 16.81\)

To find the area of a square, simply multiply the side length by itself. As \(\displaystyle 140\) is the side length, that is the number you will use. The best answer is:

\(\displaystyle 140 * 140 = 19600\)

To find the area of a square, we use the following formula:

\(\displaystyle \text{area of square} = l \cdot w\)

where l is the length and w is the width of the square. 

We know the square has a side of length 9 inches.  We also know a square has 4 equal sides.  So all sides are the same.  Knowing this, we can substitute into the equation.  We get

\(\displaystyle \text{area of square} = 9\text{in} \cdot 9\text{in}\)

\(\displaystyle \text{area of square} = 81\text{in}^2\)

To find the area of a square, we will use the following formula:

\(\displaystyle \text{area of square} = l \cdot w\)

where l is the length and w is the width of the square.

Now, we know the length of the square is 6in.  Because it is a square, we know that all sides are equal and all sides have the same length.  Therefore, the width is also 6in.  Knowing this, we can substitute into the formula.  We get

\(\displaystyle \text{area of square} = 6\text{in} \cdot 6\text{in}\)

\(\displaystyle \text{area of square} = 36\text{in}^2\)

To find the area of a square, we will use the following formula:

\(\displaystyle \text{area of square} = l \cdot w\)

where l is the length and w is the width.  

We know the square has a base of length 3 feet.  Because it is a square, we know that all sides are equal.  This means that all sides have the same length.  Therefore, the width is also 3 feet.  Knowing this, we can substitute into the formula.  We get

\(\displaystyle \text{area of square} = 3\text{ft} \cdot 3\text{ft}\)

\(\displaystyle \text{area of square} = 9\text{ft}^2\)

To find the area of a square, we will use the following formula:

\(\displaystyle \text{area of square} = l \cdot w\)

where l is the length and w is the width of the square.

Now, we know the base, or length, of the square is 3 feet.  Because it is a square, we know that all sides are equal.  Therefore, the width is also 3 feet.  Knowing this, we can substitute into the formula.  We get

\(\displaystyle \text{area of square} = 3\text{ft} \cdot 3\text{ft}\)

\(\displaystyle \text{area of square} = 9\text{ft}^2\)

To find the area of a square, we will use the following formula:

\(\displaystyle \text{area of square} = l \cdot w\)

where l is the length and w is the width of the square.

Now, we know the width of the square is 11cm.  Because it is a square, we know that all sides are equal, which means all sides are 11cm.  Therefore, the length is also 11cm.  Knowing this, we can substitute into the formula.  We get

\(\displaystyle \text{area of square} = 11\text{cm} \cdot 11\text{cm}\)

\(\displaystyle \text{area of square} = 121\text{cm}^2\)

To find the area of a square, we will use the following formula:

\(\displaystyle \text{area of square} = l \cdot w\)

where l is the length and w is the width of the rectangle.

Now, we know the width of the square is 8in.  Because it is a square, all sides are equal.  This means all sides are 8in.  Therefore, the length is 8in.  Knowing this, we can substitute into the formula.  We get

\(\displaystyle \text{area of square} = 8\text{in} \cdot 8\text{in}\)

\(\displaystyle \text{area of square} = 64\text{in}^2\)

To find the area of a square, we will use the following formula:

\(\displaystyle \text{area of square} = l \cdot w\)

where l is the length and w is the width of the square.

Now, let's look at the square.

We can see that the length is 5cm.  Because it is a square, we know that all sides are equal.  Therefore, the width is also 5cm. 

Knowing this, we can substitute into the formula.  We get

\(\displaystyle \text{area of square} = 5\text{cm} \cdot 5\text{cm}\)

\(\displaystyle \text{area of square} = 25\text{cm}^2\)
