Calculate Side Length of a Square with Area = 1: Basic Geometry Problem

Question

A square has an area of 1.

How long are its sides?

00:04 Let's find the length of a square's side.

00:07 Use the area formula: side times side equals area.

00:13 Now, plug in the area value, and solve for the side length.

00:18 To find the side, take the square root of the area.

00:26 And there you have it, that's the solution!

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:

$\sqrt{1}=L$

$L=1$

$1$
