### Example Question #1 : Squares

What is the perimeter of the square below?

**Possible Answers:**

None of the other answers

**Correct answer:**

To find the perimeter of a shape, take all of the outside measurements and add them together. There are only 2 measurements showing. However, perimeter goes all the way around the square which has four equal sides. Therefore, the measurement of the other sides must be the same and must be used to find the perimeter.

Take all four sides and add them together to find the perimeter of the square. Since each side is equally 5 inches then the total of the sides (or perimeter of the square) would be

### Example Question #1 : How To Find The Perimeter Of A Square

If the area of a square is 100 cm^{2 }then what is the length of each side? What is the perimeter of the square?

**Possible Answers:**

None of the other answers

**Correct answer:**

The given area of the square was calculated by multiplying the measurement of one side of the square by the measurement of another side of the square (which are equal measurements). Since the area was 100 cm then there was a number when multiplied to itself would be 100. The number that makes this true is 10 as

It is now known that each side of the square has a length of 10 cm and to find the perimeter of the square the length of each side must be used to find the total length around the square. Therefore, since each side is 10 cm then the perimeter can be found by adding all of the sides which would be

The perimeter of the square would be

This makes the correct answer

### Example Question #1081 : Isee Lower Level (Grades 5 6) Mathematics Achievement

What is the perimeter of a square that has a side with a length of 12 cm.?

**Possible Answers:**

**Correct answer:**

To find the perimeter of a shape, you must add up the lengths of the sides. By definition, a square has 4 equal sides. So, you only need to know the length of one side of a square in order to know the lengths of all the sides of a square.

Since the length of one side of this square is 12 cm., you can either add the lengths of the four sides together or multiply the length of one side by 4.

The units used in this answer would be cm. — not cm.^{2 }— because we are only find the length aroud the shape when solving for perimeter.

### Example Question #1 : Squares

Use the square to answer the question.

What is perimeter of the square?

**Possible Answers:**

**Correct answer:**

To find the perimeter of a square, add all the sides together:

### Example Question #1 : How To Find The Perimeter Of A Square

If the perimeter of a square is

What is the length of one of its sides?

**Possible Answers:**

**Correct answer:**

The perimeter of a shape is equal to the sum of the lengths of each side. By definition, a square has 4 equal sides. As a result, you can divde the perimeter by 4 to get the length of one side:

Since divided by equals , then is the length of one side of the square.

You can also check your answer by adding up the lengths of all the sides or by multiplying the length of one of the sides by . If you get , you are correct.

### Example Question #1 : How To Find The Perimeter Of A Square

The area of a square is . What is its perimeter?

**Possible Answers:**

5 feet

3 feet

20 feet

16 feet

25 feet

**Correct answer:**

20 feet

The area of a square is calculated by multiplying one side by itself.

If the area is 25, then the length of one side will be the square root of 25.

The square root of 25 is 5, so each side must be 5 feet long.

If each of the four sides is 5 feet long, then the perimeter would be 20 feet because there are four sides total.
