Example Question #241 : Squares
Find the perimeter of a square inscribed in a circle that has a diameter of .
Notice that the diameter of the circle is also the diagonal of the square. The diagonal of the square is also the hypotenuse of a right isosceles triangle that has the sides of the square as its legs.
Now, use the Pythagorean theorem to find the length of the sides of the square.
Now, substitute in the value of the diagonal to find the length of a side of the square.
Simplify.

Example Question #901 : Basic Geometry
Find the perimeter of a square whose side length is 7.
The perimeter of a square is found by adding all the side lengths together. In a square there are two widths, two lengths, and they are equal.
In other words, simply use the formula for the perimeter of a square and let,
To solve, simply use the formula for the perimeter of a square let,

Example Question #61 : How To Find The Perimeter Of A Square
Find the perimeter of a square with side length 2.
To solve, simply use the formula for the perimeter of a square. Thus,
Example Question #243 : Squares
Find the perimeter of a square with side length of 2.
To solve, simply use the formula for the perimeter of a square. Thus,
If the formula escapes you, simply sum the sides. However, you must know that all the sides in a square are equal in order to add them up. Since they are equal, the formula just shows you that you can multiply one side by 4 instead of adding them all together.
