There are two main ways: If you have, or can easily find the height and length of base, you can use Area=(1/2) base*height.
If you cannot find these easily, but you have an angle and two lengths, you can use the formula: Area=(1/2)a*b*sin(C)
Where a and b are two of the lengths, and C is the angle in degrees.

How do you work out a length of a triangle?
The way you can work out the length of a triangle is if you are given the height and the area of that triangle ( this works of you don't want to measure it) or you could just measure it.
How do you work out area of a triangle?
the base of the triangle multiplied by height, then that number divided by 2. A = b*h/2
How do you work out the area of a triangle?
Base x height divided by 2
How do you work out the surface area for a triangular prism?
To work out the area of the rectangular faces, you need to multiply the length by the width. You then need to multiply that answer by 3 (because there are 3 rectangular faces).To work out the area of the triangular faces, multiply the base of the triangle by the height and divide the answer by 2 (to find the area of one triangle). You then need to multiply it by 2 again because there are 2 triangular faces.Important: The height of a triangle is the distance from the top corner of the triangle down to the base (so that it meets the base at 90 degrees)You then need to add the total surface area of the rectangular faces to the surface area of the triangular faces to get the total surface area of the entire prism.(sorry for the essay :])
Can a triangle have the same perimeter and area as a parallelogram?
I don't know about the relation in the perimeters of a triangle and a parallelogram but if a triangle is on the same base on which the parallelogram is and the triangle is between the same parallel lines of the parallelogram, then the area of the triangle will be half the area of the parallelogram. That is, area of a triangle = 1/2 area of a parallelogram if the triangle is on the same base and between the same parallel lines.
How do you figure out Area of a triangle?
Turn the triangle into a square work out the area for that then half your answer ---- For an equilateral triangle, use the formula 1/2 x base x perpendicular height to work out the area.
How do you work out the area of a scalene triangle?
The area of any triangle has the same formula, which is base times height, divided by 2. A scalene triangle is a triangle with three sides of unequal length, which is not important when calculating the area.
How do you work out the area of an ABC triangle?
you just have to measure it in inches all the sidesAnother Answer:-Area of a triangle = 0.5*base*height
How do you work out a length of a triangle?
The way you can work out the length of a triangle is if you are given the height and the area of that triangle ( this works of you don't want to measure it) or you could just measure it.

How do you work out area of a triangle?
the base of the triangle multiplied by height, then that number divided by 2. A = b*h/2
How do you work out the area of a triangle?
Base x height divided by 2
How do l work out the area of a triangle?
A right triangle is easy, simply multiply the two sides and divide by two. A non-right triangle is a bit more of a challenge. You have to make it a right triangle by adding a right triangle to it. Calculate and then subtract the area of what you had to add.
What is the area of a triangle that has a base of 3.2 cm and a height of 1.3?
The area of any triangle is one-half the product of (base times height). Perhaps you can work it out from there.
What is the triangular work area in the kitchen?
The triangular work area in the kitchen is the triangle formed by the location of the kitchen sink, refrigerator and stove. There are standards for the length of this triangle.... something like between 14 and 21 feet.
How do work out the area of a right angled triangle?
A right triangle is easy, simply multiply the two sides and divide by two
If a triangle has height of 7 centimeters and a base of 4 centimeters what is the area?
The formula to find the area of a triangle is 1/2bhb = baseh = heightSo, in order to work out the area of a triangle with a base of 4cm and a height of 7cm...7 x 4 = 2828 / 2 = 14The area is 14cm2
