Example Questions

Example Question #151 : Plane Geometry

Find the perimeter of a square with side length \(\displaystyle 9\).

Possible Answers:

\(\displaystyle 18\)

\(\displaystyle 63\)

\(\displaystyle 36\)

\(\displaystyle 81\)

Correct answer:

\(\displaystyle 36\)

Explanation:

To solve, simply use the formula for the perimeter of a square. Thus,

\(\displaystyle P=4s=4*9=36\)

Example Question #152 : Plane Geometry

An easy way to find the side length of a square from the perimeter is just to divide the perimeter by \(\displaystyle 4\).  True or False?

Possible Answers:

False

True

Correct answer:

True

Explanation:

The perimeter of a square is all four sides added together.  Since each side of the square is the same value, it is adding the same number four times.  \(\displaystyle s+s+s+s=4s\) and to undue that to find the side length you would just divide by \(\displaystyle 4\).

Example Question #1101 : Isee Lower Level (Grades 5 6) Mathematics Achievement

A squares sides measure \(\displaystyle y + 1\) inches each.  What is its perimeter?

Possible Answers:

\(\displaystyle y^2 + 2y + 1\) \(\displaystyle in\)

\(\displaystyle 4y + 4\) \(\displaystyle in\)

\(\displaystyle 4\) \(\displaystyle in\)

\(\displaystyle 4y\) \(\displaystyle in\)

\(\displaystyle 8y + 4\) \(\displaystyle in\)

Correct answer:

\(\displaystyle 4y + 4\) \(\displaystyle in\)

Explanation:

To find the perimeter of any object, simply add the length of each side together.  The best answer is:

\(\displaystyle 4y + 4\)

Example Question #22 : How To Find The Perimeter Of A Square

A squares sides measure \(\displaystyle x + y\) inches each.  What is its perimeter?

 

Possible Answers:

\(\displaystyle 4x - 4y\) \(\displaystyle in\)

\(\displaystyle 8x + 8y\) \(\displaystyle in\)

\(\displaystyle 4x + 4\) \(\displaystyle in\)

\(\displaystyle 4x + 4y\) \(\displaystyle in\)

\(\displaystyle 2x + 2y\) \(\displaystyle in\)

Correct answer:

\(\displaystyle 4x + 4y\) \(\displaystyle in\)

Explanation:

To find the perimeter of any object, simply add the length of each side together.  The best answer is:

\(\displaystyle 4x + 4y\)

Possible Answers:

\(\displaystyle 15.2\) \(\displaystyle in\)

\(\displaystyle 16.2\) \(\displaystyle in\)

\(\displaystyle 18.2\) \(\displaystyle in\)

\(\displaystyle 19.2\) \(\displaystyle in\)

\(\displaystyle 17.2\) \(\displaystyle in\)

Correct answer:

\(\displaystyle 17.2\) \(\displaystyle in\)

Explanation:

To find the perimeter of any object, simply add the length of each side together.  The best answer is:

\(\displaystyle 17.2\)

Example Question #1106 : Isee Lower Level (Grades 5 6) Mathematics Achievement

A squares sides measure \(\displaystyle 28\) inches each.  What is its perimeter?

Possible Answers:

\(\displaystyle 312\) \(\displaystyle in\)

\(\displaystyle 112\) \(\displaystyle in\)

\(\displaystyle 11.2\) \(\displaystyle in\)

\(\displaystyle 212\) \(\displaystyle in\)

\(\displaystyle 224\) \(\displaystyle in\)

Correct answer:

\(\displaystyle 112\) \(\displaystyle in\)

Explanation:

To find the perimeter of any object, simply add the length of each side together.  The best answer is:

\(\displaystyle 112\)

Example Question #481 : Measurement & Data

What is the perimeter of the square below? 

Screen shot 2015 11 05 at 8.19.52 am

Possible Answers:

\(\displaystyle 15cm\)

\(\displaystyle 30cm\)

\(\displaystyle 35cm\)

\(\displaystyle 20cm\)

\(\displaystyle 25cm\)

Correct answer:

\(\displaystyle 20cm\)

Explanation:

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 \(\displaystyle P=2l+2w\), which is the same thing as adding all the side lengths together. 

\(\displaystyle P=2(5)+2(5)\) or \(\displaystyle P=5+5+5+5\)

\(\displaystyle P=20cm\)

Example Question #482 : Measurement & Data

What is the perimeter of the square below?

Possible Answers:

\(\displaystyle 15cm\)

\(\displaystyle 12cm\)

\(\displaystyle 24cm\)

\(\displaystyle 18cm\)

\(\displaystyle 21cm\)

Correct answer:

\(\displaystyle 12cm\)

Explanation:

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 \(\displaystyle P=2l+2w\), which is the same thing as adding all the side lengths together. 

\(\displaystyle P=2(3)+2(3)\) or \(\displaystyle P=3+3+3+3\)

\(\displaystyle P=12cm\)

Example Question #24 : Squares

What is the perimeter of the square below?

\(\displaystyle 35cm\)

\(\displaystyle 21cm\)

\(\displaystyle 14cm\)

\(\displaystyle 42cm\)

\(\displaystyle 28cm\)

Correct answer:

\(\displaystyle 28cm\)

Explanation:

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 \(\displaystyle P=2l+2w\), which is the same thing as adding all the side lengths together. 

\(\displaystyle P=2(7)+2(7)\) or \(\displaystyle P=7+7+7+7\)

\(\displaystyle P=28cm\)
