A square has one side of length 
, what is the length of the opposite side?
A square has one side of length
One of the necessary conditions of a square is that all sides be of equal length. Therefore, because we are given the length of one side we know the length of all sides and that includes the length of the opposite side. Since the length of one of the sides is 4 we can conclude that all of the sides are 4, meaning the opposite side has a length of 4.

The diagonal of a square has a length of 10 inches. What is the perimeter of the square in inches squared?
The diagonal of a square has a length of 10 inches. What is the perimeter of the square in inches squared?
Using the Pythagorean Theorem, we can find the edge of a side to be √50, by 2a2=102. This can be reduced to 5√2. This can then be multiplied by 4 to find the perimeter.

A square garden has an area of 64 square feet. If you add 3 feet to each side, what is the new perimeter of the garden?
A square garden has an area of 64 square feet. If you add 3 feet to each side, what is the new perimeter of the garden?
By finding the square root of the area of the garden, you find the length of one side, which is 8. We add 3 feet to this, giving us 11, then multiply this by 4 to get 44 feet for the perimeter.

Find the perimeter of a square with side length of 2.
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.

Are these rectangles similar?
Are these rectangles similar?
To determine if the rectangles are similar, set up a proportion comparing the short sides and the long sides from each rectangle:
cross-multiply
since that's true, the rectangles are similar.
To find the scale factor, either divide 25 by 10 or 7.5 by 3. Either way you will get 2.5.

If the area of a square is 12.25 square meters, what is its perimeter?
If the area of a square is 12.25 square meters, what is its perimeter?
The area of a square is found by squaring the length of each side. That means we can figure out the length of the sides by taking the square root of 12.25. 
The length of all 4 sides is 3.5 meters, since this is a square, so the perimeter is

A square is circumscribed on a circle with a 6 inch radius. What is the area of the square, in square inches?
A square is circumscribed on a circle with a 6 inch radius. What is the area of the square, in square inches?
We know that the radius of the circle is also half the length of the side of the square; therefore, we also know that the length of each side of the square is 12 inches.
We need to square this number to find the area of the square.
