How To Calculate Area Of A Triangle
Whether you're carpeting a room, hanging wallpaper or shingling a roof, you may need to calculate the area of a triangle. Knowing the correct formula will make your job easier and save you time by avoiding mistakes. If it's been a while since your last math class, you may need help remembering how to calculate the area of a triangle.
Step 1
Use the formula base (b) times height (h) divided by 2 to calculate the area of a triangle (b x h / 2).
Step 2
Choose any side of the triangle as the base. If it's right triangle, use one of the sides forming the right angle.
Step 3
Measure the length of the base.
Step 4
Find the height of the triangle. The height is not necessarily one of the triangle's sides. The height will always be at a right angle, or perpendicular, to the base. Measure the height.
Step 5
Multiply the base times the height.
Step 6
Take the number that you calculated in Step 5 and divide it by 2. This will give you the area of the triangle, or the total square measurement.
TL;DR (Too Long; Didn't Read)
Create a basic diagram of the triangle to help you visualize the base side and height of the triangle.
