Calculate Side Length: Finding Square Root of Area 36

Question

A square has an area of 36.

How long are its sides?

00:00 Find the side of the square

00:03 Use the formula for calculating the area of a square (side squared)

00:08 Substitute appropriate values and solve for the side

00:15 Extract the root

00:23 And this is the solution to the question

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:

$\sqrt{36}=a$

$6=a$

$6$
