Area of the Square: Calculate The Missing Side based on the formula

Remember that the area of the square is equal to the side of the square raised to the second power.

The formula for the area of the square is:

$A=L^2$

We calculate the area of the square:

$4=L^2$

We extract the square root:

$\sqrt{4}=L$

$2=L$

Remember that the area of the square is equal to the side of the square raised to the 2nd power.

We substitute the data into the formula:

$100=L^2$

Then we calculate the root:

$\sqrt{100}=L$

$L=10$

Remember that the area of the square is equal to the side of the square raised to the 2nd power.

Now we replace the data in the formula:

$121=L^2$

We extract the root:

$\sqrt{121}=L$

$L=11$

Remember that the area of a square is equal to the side of the square raised to the 2nd power.

We replace the data in the formula:

$144=L^2$

Then we calculate the root:

$\sqrt{144}=L$

$L=12$

Remember that the area of a square is equal to the side of the square raised to the 2nd power.

We substitute the data into the formula:

$169=L^2$

We calculate the root:

$\sqrt{169}=a$

$L=13$

Remember that the area of a square is equal to the side of the square squared.

The formula for the area of a square is:

$S=a^2$

Calculate the area of the square:

$16=a^2$

Calculate the square root:

$\sqrt{16}=a$

$4=a$

Remember that the area of the square is equal to the side of the square raised to the 2nd power.

Now, we replace the data in the formula:

$1=L^2$

We extract the root:

$\sqrt{1}=L$

$L=1$

Remember that the area of a square is equal to the side of the square raised to the 2nd power.

Now, we replace the data in the formula:

$25=L^2$

We extract the square root:

$\sqrt{25}=L$

$L=5$

Remember that the area of a square is equal to the side of the square squared

The formula for the area of a square is:

$S=a^2$

Let's calculate the area of the square:

$36=a^2$

Let's take the square root:

$\sqrt{36}=a$

$6=a$

The area of the square is equal to the length of the square raised to the second power.

That is:

$A=L^2$

Since we know that the area of the square is equal to 400, we perform the formula as follows:

$400=L^2$

We solve the square root:

$\sqrt{400}=L$

$L=20$

The side of the square is equal to 20.

Since the area of the square is equal to the side raised to the 2nd power, we use the formula to find the side:

$49=a^2$

$a=7$

Remember that the area of a square is equal to the side of the square raised to the second power.

Now we substitute the data into the formula:

$64=L^2$

Then, we calculate the square root:

$\sqrt{64}=L$

$L=8$

Remember that the area of a square is equal to the side of the square raised to the second power.

Formula for the area of the square:

$A=L^2$

We calculate the area of the square:

$81=L^2$

We calculate the root:

$\sqrt{81}=a$

$9=a$

Remember that the area of a square is equal to the side of the square raised to the 2nd power.

Now, we replace the data in the formula:

$900=L^2$

We extract the root:

$\sqrt{900}=L$

$L=30$

Remember that the area of the square is equal to the side of the square raised to the second power.

The formula for the area of the square is:

$A=L^2$

We calculate the area of the square:

$9=a^2$

We extract the root:

$\sqrt{9}=L$

$3=L$

The area of the large square is:
$10^2=100$

The area of the small square is 25.

$\frac{100}{25}=4$

The square root of 4 is equal to 2.

We will call X the length of the side:

$\frac{10}{x}=2$

$2x=10$

$x=5$
