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?

00:00 Find the side of the square

00:03 Use the formula to calculate the area of a square (side squared)

00:08 Substitute appropriate values and solve for the side

00:14 Take the square root

00:22 And this is the solution to the problem

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:

$\sqrt{1}=L$

$L=1$

$1$
