area of a square is 256 cm2

To find the side length of the square, we can take the square root of the area.

√(256 cm²) = 16 cm

To find the area of the square, we can square the side length.

(16 cm)² = 256 cm²

So, the area of the square is 256 cm².

To find the side length of a square with an area of 256 cm^2, you can use the formula for the area of a square, which is side length squared.

Let's assume the side length of the square is "x" cm.

We can write the equation as follows:

x^2 = 256 cm^2

To solve for "x," we will take the square root of both sides:

√(x^2) = √256 cm^2

Simplifying the equation:

x = √256 cm

Now, we can calculate the square root of 256:

x = 16 cm

Therefore, the side length of the square is 16 cm.

To find the area of a square, you need to square the length of one of its sides. In the given question, you are told that the area of the square is 256 cm².

To find the length of one side, you need to take the square root of the given area.

Let's use the square root function (√) to find the length of one side:
√(256 cm²) = 16 cm

Therefore, the length of one side of the square is 16 cm.

To double-check, you can also compute the area by squaring the side length:
16 cm * 16 cm = 256 cm²

So the length of one side of the square is 16 cm, and its area is 256 cm².
