To solve this problem, we need to remember is that a square has four sides of equal length. This means that given one side length, we know all the other side lengths. The formula for perimeter is , which is the same thing as adding all the side lengths together.

To find the perimeter of any object, simply add the length of each side together.  With a square, all of the sides are uniform, so you can take the side length and multiply it by four (or add it to itself four times). The best answer is:

To find the perimeter of a square, we will use the following formula:

where a, b, c, and d are the lengths of the sides of the square.

Now, we know the width of the square is 7ft.  Because it is a square, we know that all sides are equal.  This means that all sides have the same length.  Therefore, every side is 7ft.  Knowing this, we can substitute into the formula.  We get

To find the perimeter of a square, we will use the following formula:

where a, b, c, and d are the lengths of the sides of the square.

We know the base of this square has a length of 8 inches.  Because it is a square, we know that all sides are equal.  This means that all sides are the same length.  Therefore, all sides are 8 inches.  Knowing this, we can substitute into the formula.  We get

To find the perimeter of a square, we will use the following formula:

where a, b, c, and d are the lengths of the sides of the square.

Now, we know the base of the square has a length of 7in.  Because it is a square, we know that all sides are equal.  Therefore, all sides have a length of 7in.  Knowing this, we can substitute into the formula.  We get
