Example Questions

Example Question #291 : Squares

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

Possible Answers:

\(\displaystyle 34\)

\(\displaystyle 289\)

\(\displaystyle 34\)

\(\displaystyle 192\)

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.

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

\(\displaystyle 64\)

\(\displaystyle 48\)

\(\displaystyle 16\)

\(\displaystyle 32\)

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.

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

\(\displaystyle 48\)

\(\displaystyle 74\)

\(\displaystyle 37\)

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 #294 : Squares

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

Possible Answers:

\(\displaystyle 27\)

\(\displaystyle 81\)

\(\displaystyle 9\)

\(\displaystyle 54\)

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 #295 : Squares

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

Possible Answers:

\(\displaystyle 18\)

\(\displaystyle 38\)

\(\displaystyle 21\)

\(\displaystyle 19\)

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.

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

Possible Answers:

\(\displaystyle 26\)

\(\displaystyle 28\)

\(\displaystyle 22\)

\(\displaystyle 24\)

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 #542 : Quadrilaterals
