How to find the area of a right triangle - Math

The area of a triangle is denoted by the equation 1/2 b x h.

b stands for the length of the base, and h stands for the height.

Here we are told that the perimeter (total length of all three sides) is 12, and the hypotenuse (the side that is neither the height nor the base) is 5 units long.

So, 12-5 = 7 for the total perimeter of the base and height.

7 does not divide cleanly by two, but it does break down into 3 and 4,

and 1/2 (3x4) yields 6.

Another way to solve this would be if you recall your rules for right triangles, one of the very basic ones is the 3,4,5 triangle, which is exactly what we have here

The base is equal to 6.

The height of an quilateral triangle is equal to , where is the length of the base.

The area of a triangle is given by the equation:

Since the base leg of the given triangle is 4 cm, while the height is 3 cm, this gives:

An equilateral triangle has three congruent sides. The area of a triangle is given by where is the base and is the height.

The equilateral triangle can be broken into two right triangles, where the legs are and and the hypotenuses is .

Using the Pythagorean Theorem we get or and the area is

The formula for the area of a triangle is

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

For the triangle shown, side is the base and side is the height.

Therefore, the area is equal to

or, based on the units given, 42 square centimeters

In a , the shorter leg is half as long as the hypotenuse, and the longer leg is times the length of the shorter. Since the hypotenuse is 8, the shorter leg is 4, and the longer leg is , making the area:

To find the area of a right triangle, use the formula , where is the area of the triangle, is the length of the triangle's base, and is the triangle's height.

To find the area of a triangle, multiply the base by the height, then divide by 2.

The equation used to find the area of a right triangle is: where A is the area, b is the base, and h is the height of the triangle. In this question, we are given the height, so we need to figure out the base in order to find the area. Since we know both the height and hypotenuse of the triangle, the quickest way to finding the base is using the pythagorean theorem, . a = the height, b = the base, and c = the hypotenuse.

Using the given information, we can write . Solving for b, we get or . Now that we have both the base and height, we can solve the original equation for the area of the triangle.

The area of a triangle is . For a right triangle, we can use the two legs as the base and the height regardless of orientation. Right now we only know one of the legs, and we can solve for the other using Pythagorean Theorem:

subtract 16 from both sides

we can see that all of the answers are in radical form, so we do not have to simplify this to a crazy decimal.

Now we have our "base" and "height" and we can plug them into the formula to find the area:

half of 4 is 2, so our answer is , which we can't simplify any more.

The area of a triangle is found using the formula . For a right triangle, we can use the two legs as the base and height regardless of the orientation of the triangle.

In this case, we only know one leg, but we can figure out the other by using the Pythagorean Theorem:

subtract 36 from both sides

take the square root

Now that we have our "base" and "height," we can substitute them into the formula and find the area:

To find area of this triangle, you must use the formula indicated below.

where is base and is height. Thus:
