Each side length of the square is

Step-by-step explanation:

We know that a square has 4 Equal sides.

To find the area of a triangle, you will have to use the formula

Then, you will substitute with 4 and 16.

(x=times)

Then, simplify.

Then, simplify again :)

Now, we know that the area of a triangle is . It tells us that the area of a square is double that.

So, we divide by , since a square has 4 sides.

Hence, one side length of a square is .

Hope that helps:D
