If the triangle is right-angled then you should be able to use Pytharoras Theorem to calculate the missing side
otherwise you need an angle to be able to use trigonometry
The height and base are not sufficient to uniquely identify the sides of a triangle - there are an infinite number of possibilities.
The area of a triangle is base x height / 2. Height should be perpendicular to base.
Depends on the length of the sides ! The simple formula to calculate the area of a triangle is half the base times the height.
-- Imagine what you have if you slice the triangle in half along the height ...-- You have a right triangle. One side of it is 1/2 of the base, and one side isthe height.-- The slanting side is the hypotenuse of the right triangle, and knowing whatyou know about right triangles, you can calculate its length.-- Once you do that, you have the lengths of all three sides of the original triangle,and you can calculate the perimeter.
These are basically the steps: * Use the formula for the area of a triangle to calculate the height. * Use the height and half the base to calculate the lateral sides. Use the Pythagorean Theorem. (It helps to draw a sketch, to visualize the situation.) * Add the three sides to get the perimeter.
If you know the length of the sides, you can use Pythagoras' Theorem to calculate the height. Use half the base for one of the shorter sides, and either of the two identical sides of the triangle for the hypothenuse. Solve for the other one of the shorter sides (the height).

Half The Base, Times The Height Of The Triangle.
The area of a triangle is base x height / 2. Height should be perpendicular to base.
That depends on what you know about the triangle. The easiest way to calculate the area is to calculate (1/2) x base x height, where the base is any side, and the height is perpendicular to the base. Other formulae exist for special cases, for example, for the case that you only know the length of the three sides.

If it is a right angled triangle then it is 0.5*(base)*(height) of the triangle half the base times by the height imagine it as half the area of a rectangle of the two triangles * * * * * That is all very well if you know the base and the height. Sometimes you know only the three sides. Or only two sides and an angle, or two angle and a side. There are a whole host of formulae for such circumstances.
Depends on the length of the sides ! The simple formula to calculate the area of a triangle is half the base times the height.
The side you use as the base does not matter. What does matter is that the height is the perpendicular distance between this side and the other vertex. If there is a right angle in the triangle, then use the two sides next to it as the base and height. Otherwise a bit of trigonometry will be required to work out the height of the triangle if it is not given.

Height will be h=base*tan(angle).
