Example Question #413 : Geometry

Use the following rectangle to answer the question:

Rectangle1

Find the area.

Possible Answers:

Correct answer:

Explanation:

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

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

 

Now, let's look at the rectangle.

Rectangle1

We can see the length of the rectangle is 6in. We can also see the width of the rectangle is 3in. 

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

Example Question #414 : Geometry

Use the following rectangle to solve the problem:

Rectangle2

Find the area.

Possible Answers:

Correct answer:

Explanation:

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

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

 

Now, given the rectangle

Rectangle2

we can see the length is 11in and the width is 5in.  So, we can substitute.  We get

 

Example Question #421 : Geometry

Find the area of the rectangle.

The rectangle has a length of 12cm and a width of 7cm.

Possible Answers:

Correct answer:

Explanation:

The formula to solve for the area of a rectangle is length multiplied by width.  

In this case that would be (12cm x 7cm).  

12 x 7 is 84.  

84 is then your answer. To finish your answer off with a label, you take (cm x cm) and that is where you get .

So your final answer is .

Example Question #422 : Geometry

Find the area of the following rectangle.

The length of the rectangle is three times the width of the rectangle. The width of the rectangle is 3cm.

Possible Answers:

Correct answer:

Explanation:

First you must figure out the length of the rectangle.

The length was 3 times the width.  

The width was 3cm, so 3 x 3 = 9.  

The length of the rectangle is 9cm.  Now that you have your length and width, you are able to use the formula to find the area of a rectangle which is length times width. 

 and ,

so your answer is .

Example Question #423 : Geometry

Find the area of the rectangle.

The width of the rectangle is half the length of the rectangle. The length of the rectangle is 12cm.

Possible Answers:

Correct answer:

Explanation:

First you must find the width of the rectangle which is half of the length.

So our width is 6cm.  Then you use the formula to solve for the area of a rectangle which is length times width.
