Example Questions

Example Question #261 : Geometry

Find the area of a square with a length of 13in.

Possible Answers:

Correct answer:

Explanation:

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

where l is the length and w is the width of the square.

 

Now, we know the length of the square is 13in.  Because it is a square, all sides are equal.  Therefore, the length is also 13in.

Knowing this, we can substitute into the formula.  We get

Example Question #111 : Squares

Find the area of a square with a length of 11in.

Possible Answers:

Correct answer:

Explanation:

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

where l is the length and w is the width of the square.

 

Now, we know the length of the square is 11in.  Because it is a square, all sides are equal.  Therefore, the width is also 11in.

Knowing this, we can substitute into the formula.  We get

Example Question #1201 : Isee Lower Level (Grades 5 6) Mathematics Achievement

Find the length of one side of a square with an area of 64in.

Possible Answers:

Correct answer:

Explanation:

The formula to find area of a square is

where x is the length of one side of a square.  Now, to find the length of a side, we will solve for x.

 

So, we know the area of the square is 64in.  Knowing this, we can substitute into the formula.  We get

 

 

 

 

Therefore, the length of one side of the square is 8in.

Example Question #46 : How To Find The Area Of A Square

Find the area of a square with a width of 7cm.

Possible Answers:

Correct answer:

Explanation:

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

where l is the length and w is the width of the square.

 

Now, we know the width of the square is 7cm.  Because it is a square, all sides are equal.  Therefore, the length is also 7cm.  So, we get
