The question only is looking for a part of the picture, just the square. With squares, the rule is that all the sides are equivalent, meaning the same lengths and all angles are right angles. 

Perimeter means adding up all the sides together. So we just need to add the lengths of the sides of the square. Uh oh, we only have one side that is listed.

Again, remember that with squares the sides are equivalent, and we know one side is 5 inches. We just need to take \(\displaystyle 5+5+5+5\) because a square has 4 sides. 

Our perimeter is \(\displaystyle {20}''\).

When Sandy puts the border around her son's room, she will need enough to cover the perimeter.  Since the room has four walls equal in length, we know that the room is a square.  The perimeter of a square can by found by adding all the sides together, or by multiplying the length of one side by 4.  This can be written as:

\(\displaystyle \small \small 4s=P\)

Since we know that Sandy used \(\displaystyle \small 36\) feet of border, we know the perimeter is \(\displaystyle \small 36\). We can now write an equation:

\(\displaystyle \small 4s=36\)

Now, in order to isolate the variable, we can divide both sides by four.

The left-hand side simplifies to:

\(\displaystyle \small \small \frac{4s}{4}=s\)

The right-hand side simplifies to:

\(\displaystyle \small \frac{36}{4}=9\)

\(\displaystyle \small s=9 \: feet\)

When we solve, we find that the length of each wall is \(\displaystyle \small 9 \: feet\).

The perimeter is equal to the sum of the length of all sides. Each side is equal to \(\displaystyle \small 9\). Therefore, the perimeter equals:

\(\displaystyle \small P=9+9+9+9=36\)

To solve, simply multiply the side length by 4 since all sides in a square area equal. Thus,

\(\displaystyle P=4s=4*10=40\)

A new building in New York City will have a footprint that is a perfect square, taking up a complete city block. If one city block is \(\displaystyle 1/8\)of a mile, what is the perimeter of the building?

To find the perimeter of a square, we need to multiply the side length by 4.

Our side length is \(\displaystyle 1/8\) mile, so do the following to find our answer:

\(\displaystyle 4*\frac{1}{8}=\frac{4}{8}=\frac{1}{2}mi\)

So the perimeter is \(\displaystyle \frac{1}{2}mi\)

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

\(\displaystyle \text{perimeter of square} = a+b+c+d\)

where a, b, c, and d are the lengths of each side. 

Now, we know that a square has equal sides.  So given the square

we know that each side equals 6ft.  So, we can use this to substitute into the formula.  We get

\(\displaystyle \text{perimeter of square} = 6\text{ft} + 6\text{ft} + 6\text{ft} + 6\text{ft}\)

\(\displaystyle \text{perimeter of square} = 24\text{ft}\)

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

\(\displaystyle \text{perimeter of square} = a+b+c+d\)

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

Now, we know the width of the square is 8 inches.  Because it is a square, we know all sides are equal.  Therefore, all sides are 8 inches.  Knowing this, we can substitute into the formula.  We get

\(\displaystyle \text{perimeter of square} = 8\text{ inches} +8\text{ inches} +8\text{ inches} +8\text{ inches}\)

\(\displaystyle \text{perimeter of square} = 32 \text{ inches}\)

You are playing Monopoly and notice that the dice is a cube. If the dice has a height of 2 centimeters, what is the perimeter of one of its surfaces?

Begin by realizing that we need to find the perimeter of a square.

Next, recall that the height of a cube is the same as its length and width. In other words, one surface of a cube will be a square with sides equal to the height of the cube.

Armed with this knowledge, we can find the perimeter of the square.

\(\displaystyle P=4s\)

\(\displaystyle P=4*2cm=8cm\)

So our answer is 8cm

A square stamp has an edge length of 6 centimeters, what is its perimeter?

To find the perimeter of a square, we simply can multiply the edge length by 4.

Doing so yields:

\(\displaystyle P_{square}=6cm*4=24cm\)

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

\(\displaystyle \text{perimeter of square} = a+b+c+d\)

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

Now, we know the base has a length of 9 inches.  Because it is a square, we know that all sides are equal.  Therefore, all sides are 9 inches.  Knowing this, we can substitute into the formula.  We get

\(\displaystyle \text{perimeter of square} = 9\text{in} +9\text{in} +9\text{in} +9\text{in}\)

\(\displaystyle \text{perimeter of square} = 36\text{in}\)
