Example Questions

Example Question #291 : Squares

The perimeter of a square is \(\displaystyle 328\). What is the length of one side of the square?

Possible Answers:

\(\displaystyle 72\)

\(\displaystyle 82\)

\(\displaystyle 86\)

\(\displaystyle 98\)

Correct answer:

\(\displaystyle 82\)

Explanation:

Recall how to find the perimeter of a square:

\(\displaystyle \text{Perimeter}=4(\text{side length})\)

By dividing both sides by \(\displaystyle 4\), we can write the following:

\(\displaystyle \text{Side length}=\frac{\text{Perimeter}}{4}\)

For the square in question,

\(\displaystyle \text{Side length}=\frac{328}{4}\)

\(\displaystyle \text{Side length}=82\) 

Example Question #292 : Squares

Find the length of a side of a square that has an area of \(\displaystyle 1156\).

Possible Answers:

\(\displaystyle 34\)

\(\displaystyle 192\)

\(\displaystyle 34\)

\(\displaystyle 289\)

Correct answer:

\(\displaystyle 34\)

Explanation:

Recall how to find the area of a square:

\(\displaystyle \text{Area}=\text{side length}^2\)

We can rewrite that equation into the following:

\(\displaystyle \text{side length}=\sqrt{\text{Area}}\)

Now, plug in the given area to find the side length of the square.

\(\displaystyle \text{Side length}=\sqrt{1156}=34\)

Example Question #293 : Squares

If the area of a square is \(\displaystyle 256\), find the length of one side of the square.

Possible Answers:

\(\displaystyle 32\)

\(\displaystyle 64\)

\(\displaystyle 48\)

\(\displaystyle 16\)

Correct answer:

\(\displaystyle 16\)

Explanation:

Recall how to find the area of a square:

\(\displaystyle \text{Area}=\text{side length}^2\)

We can rewrite that equation into the following:

\(\displaystyle \text{side length}=\sqrt{\text{Area}}\)

Now, plug in the given area to find the side length of the square.

\(\displaystyle \text{Side length}=\sqrt{256}=16\)

Example Question #951 : Basic Geometry

If the area of a square is \(\displaystyle 1369\), find the length of one side of the square.

Possible Answers:

\(\displaystyle 18\)

\(\displaystyle 48\)

\(\displaystyle 74\)

\(\displaystyle 37\)

Correct answer:

\(\displaystyle 37\)

Explanation:

Recall how to find the area of a square:

\(\displaystyle \text{Area}=\text{side length}^2\)

We can rewrite that equation into the following:

\(\displaystyle \text{side length}=\sqrt{\text{Area}}\)

Now, plug in the given area to find the side length of the square.

\(\displaystyle \text{Side length}=\sqrt{1369}=37\)

Example Question #952 : Basic Geometry

If the area of a square is \(\displaystyle 729\), find the length of one side of the square.

Possible Answers:

\(\displaystyle 9\)

\(\displaystyle 27\)

\(\displaystyle 81\)

\(\displaystyle 54\)

Correct answer:

\(\displaystyle 27\)

Explanation:

Recall how to find the area of a square:

\(\displaystyle \text{Area}=\text{side length}^2\)

We can rewrite that equation into the following:

\(\displaystyle \text{side length}=\sqrt{\text{Area}}\)

Now, plug in the given area to find the side length of the square.

\(\displaystyle \text{Side length}=\sqrt{729}=27\)

Example Question #953 : Basic Geometry

If the area of a square is \(\displaystyle 361\), find the length of one side of the square.

Possible Answers:

\(\displaystyle 19\)

\(\displaystyle 38\)

\(\displaystyle 18\)

\(\displaystyle 21\)

Correct answer:

\(\displaystyle 19\)

Explanation:

Recall how to find the area of a square:

\(\displaystyle \text{Area}=\text{side length}^2\)

We can rewrite that equation into the following:

\(\displaystyle \text{side length}=\sqrt{\text{Area}}\)

Now, plug in the given area to find the side length of the square.

\(\displaystyle \text{Side length}=\sqrt{361}=19\)

Example Question #954 : Basic Geometry

If the area of a square is \(\displaystyle 676\), find the length of one side of the square.

Possible Answers:

\(\displaystyle 26\)

\(\displaystyle 24\)

\(\displaystyle 22\)

\(\displaystyle 28\)

Correct answer:

\(\displaystyle 26\)

Explanation:

Recall how to find the area of a square:

\(\displaystyle \text{Area}=\text{side length}^2\)

We can rewrite that equation into the following:

\(\displaystyle \text{side length}=\sqrt{\text{Area}}\)

Now, plug in the given area to find the side length of the square.

\(\displaystyle \text{Side length}=\sqrt{676}=26\)

Example Question #955 : Basic Geometry

If the area of a square is \(\displaystyle 4624\), find the length of one side of the square.

Possible Answers:

\(\displaystyle 68\)

\(\displaystyle 66\)

\(\displaystyle 78\)

\(\displaystyle 62\)

Correct answer:

\(\displaystyle 68\)

Explanation:

Recall how to find the area of a square:

\(\displaystyle \text{Area}=\text{side length}^2\)

We can rewrite that equation into the following:

\(\displaystyle \text{side length}=\sqrt{\text{Area}}\)

Now, plug in the given area to find the side length of the square.

\(\displaystyle \text{Side length}=\sqrt{4624}=68\)

Example Question #956 : Basic Geometry
