Example Question #4 : Area Of A Triangle
A triangle has a height of 9 inches and a base that is one third as long as the height. What is the area of the triangle, in square inches?
None of these
The area of a triangle is found by multiplying the base times the height, divided by 2.
Given that the height is 9 inches, and the base is one third of the height, the base will be 3 inches.
We now have both the base (3) and height (9) of the triangle. We can use the equation to solve for the area.
The fraction cannot be simplified.
Example Question #51 : Geometry
The hypotenuse of a right triangle is feet; it has one leg feet long. Give its area in square inches.
The area of a right triangle is half the product of the lengths of its legs, so we need to use the Pythagorean Theorem to find the length of the other leg. Set :
The legs have length and feet; multiply both dimensions by to convert to inches:
inches
inches.
Now find half the product:
Example Question #101 : Geometry
What is the area (in square feet) of a triangle with a base of feet and a height of feet?
The area of a triangle is found by multiplying the base times the height, divided by .
Example Question #11 : Triangles
What is the area of a triangle with a base of and a height of ?
The formula for the area of a triangle is .
Plug the given values into the formula to solve:
Example Question #15 : How To Find The Area Of A Triangle
Give the perimeter of the above triangle in feet.
The perimeter of the triangle - the sum of the lengths of its sides - is
inches.
Divide by 12 to convert to feet:
As a fraction, this is or feet,
Example Question #11 : Plane Geometry
The above diagram shows Rectangle , with midpoint of .
The area of is 225. Evaluate
is the midpoint of , so has as its base ; its height is .
Its area is half their product, or
Set this equal to 225:
.
Example Question #17 : Plane Geometry
Find the area of a triangle with a height of 12in and a base that is half the height.
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 height of the triangle is 12in. We also know the base of the triangle is half of the height. Therefore, the base of the triangle is 6in.
So, we can substitute. We get
Example Question #21 : Plane Geometry
Find the area of the triangle below
The equation for area of a triangle is
.
In this case the coordinates of the base are , which means the length of the base is .
The coordinates of the side that determines the height are .
Therefore the height is .
.
Example Question #1 : How To Find Perimeter Of A Triangle
The perimeter of an isosceles triangle is 18. What is a possible list of the lengths of the sides?
Since it is isosceles, 2 of the sides must be equal. They must also add to 18.
Example Question #2 : How To Find Perimeter Of A Triangle
An equilateral triangle has perimeter 8 feet 6 inches. How long is one side?
3 feet 4 inches
3 feet 2 inches
2 feet 2 inches
2 feet 6 inches
2 feet 10 inches
2 feet 10 inches
One foot is equal to 12 inches, so the perimeter 8 feet 6 inches is equal to inches.
An equilateral triangle has three sides of equal measure, so divide its perimeter by 3:
To convert 34 inches to feet and inches:
One side measures 2 feet 10 inches.
