Find the area of a square with a base of length 8 inches.

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 base has a length of 8 inches.  Because it is a square, we know that all sides are equal.  Therefore, all sides have a length of 8 inches.  This means the width is also 8 inches.  Knowing this, we can substitute into the formula.  We get

Example Question #141 : Plane Geometry

Find the area of a square with a base of 12 inches.

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 base of the square is 12in.  Because it is a square, we know that all sides are equal.  Which means all sides are 12in.  Therefore, the width is also 12in.  Knowing this, we can substitute into the formula.  We get

Example Question #142 : Plane Geometry

Find the area of a square with a width of 5 feet.

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 rectangle.

 

Now, we know the width is 5 feet.  Because it is a square, all sides are equal.  This means the length is also 5 feet.

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

Example Question #143 : Plane Geometry

Find the area of a square with a width of 12cm.

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 12cm.  Because it is a square, all sides are equal.  Therefore, the length is also 12cm.

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

Example Question #144 : Plane Geometry

Use the following image to answer the question:

Square3

Find the area of the square.

Possible Answers:

Correct answer:

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

 

Now, let's look at the given square.

Square3

We can see the width is 8cm.  Because it is a square, we know that all sides are equal.  Therefore, the width is also 8cm.

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

Example Question #145 : Plane Geometry

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 will substitute into the formula.  We get

Example Question #26 : How To Find The Area Of A Square
