You multiply the base and the height and then you divide the answers of that by 2. :)
The formula for finding the area of a triangle is: Area = (base * height) / 2.
length times width times height
we dont know
If you know any two angles and a side, you can use the law of sine (or law of cosine) to find the other two sides, add them up and get the perimeter. It you know the base and height, you can use the Pythagorean Theorem to get the side lengths, add them up and get the perimeter.
There are different formula for: Height, Area, Perimeter, Angle, Length of Median Radius of inscribed circle Perimeter of inscribed circle Area of inscribed circle etc.
The formula for finding out perimeters of shapes is length+length+height+height=perimeter or what else you can do is (lengthx2)+(heightx2)=PERIMETER
using a protractor
(pi)r2x height divided by 2
The formula for finding the area of a triangle is: Area = (base * height) / 2.
Area = 0.5 x base x height Perimeter = side 1 + side 2 + side 3 Formula for Area of a triangle is A = bh/2, where A is Area, b is base, and h is heigth. Formula for finding the perimeter is P = s1 + s2 + s3, where s represent side, or P = AB + BC + AC where the letters represent the sides.
length times width times height
The area of a Parallelogram is Base * Height The Perimeter is 2(side1 + side2)
The area of any triangle is1/2 of (the length of the triangle's base) times (the triangle's height).

to find the area of a triangle you divide the base of the triangle by two and multiply your answer by the height .so your formula would be 1/2b times h to find the perimeter of a triangle u simply just add the sides.
