Example Question #7 : How To Find The Area Of A Triangle
If a triangle has a base of 1 foot, and a height of half a foot, what is the area in square inches?
The area of a triangle is found by multiplying the base times the height, divided by 2.
Since we are looking for the area in inches, we must convert the base and height to inches, from feet.
This gives us a base of 6 inches and a height of 12 inches. Plug these values into the area equation and solve.
Example Question #302 : Geometry
What is the area of a triangle for which the base is 9 inches and the height is 12 inches?
The area of a triangle is found by multiplying the base times the height, divided by 2.
Given that the base is 9 inches and the height is 12 inches, plugging these numbers into the equation gives us the following:
Example Question #12 : How To Find The Area Of A Triangle
If a triangle has a height of 2 inches and a base that is 3 times as long, what is the area?
The area of a triangle is found by multiplying the base times the height, divided by 2.
Given that the height is 2 inches, and the base is 3 times that of the height, the base is 6 inches.
Example Question #13 : How To Find The Area Of A Triangle
If the area of a triangle is 15 feet and the height is 5 feet, what is the length of the base?
The area of a triangle is found by multiplying the base times the height, divided by 2.
Each side of the equation should be multiplied by 2.
Each side should be divided by 5.
Therefore, the base has a value of 6.
Example Question #11 : How To Find The Area Of A Triangle
A triangle has a height of 6 inches and a base of 3 inches. What is the area, in square inches?
The area of a triangle is found by multiplying the base times the height, divided by 2.
Here, the base is 3 inches and the height is 6 inches. When plugging this information into the formula, we get:
This fraction reduces to 9, the correct answer.
