Example Question #25 : How To Find The Area Of A Triangle

Use the following to answer the question.

Triangle3

Find the area of the triangle if the height is twice the length of the base.

Possible Answers:

Correct answer:

Explanation:

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

where b is the base and h is the height of the triangle.

 

So, using the triangle

Triangle3

we can see that the base is 5cm.  The problem also stated that the height is twice (or two times) the length of the base.  So, the height is 10cm ( 2x5cm ). Knowing this, we can substitute into the formula.  We get

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

Example Question #28 : How To Find The Area Of A Triangle

Find the area of a triangle with a base of 8in and a height of 12in.

Possible Answers:

Correct answer:

Explanation:

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

where b  is the base and h is the height of the triangle.

 

Now, we know the base of the triangle is 8in.  We also know the height of the triangle is 12in.

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

Example Question #29 : How To Find The Area Of A Triangle

Find the area of a triangle with a base of 6in and a height that is three times the base.

Possible Answers:

Correct answer:

Explanation:

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

where b  is the base and h is the height of the triangle.

 

Now, we know the base of the triangle is 6in.  We also know the height of the triangle is three times the base.  Therefore, the height is 18in. 

Now, we can substitute.  We get
