You can only find the area of the base with this information. The volume divided by the height will give you the area of the base.

Assuming you know the angle of ascension, and the base, you can calculate the height by recalling that tangent theta is height over base. Simple algebra from there: height is tangent theta times base.

If you know the area, divide by the half the base. A = 1/2 b x hYou need to know at least one of its acute angles and then use trigonometry to find its height.The answer depends on what information about the triangle you do have.

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.

area = 1/2 base * perpendicular height you can't find both the base and the height if you only know the area

Volume = Base Area * Height So Height = Volume/Base Area

If you know the total area and the height are known, you can find the base. Area=(1/2)(base)(height), so if you know the height and area you can solve for the base. So now, Base=Area/(1/2)(height)

Divide the volume by the base area to determine height.

volume/height=base area.

You multiply the height and base then divide by 2.

Find the area of the base

Area = 0.5*base*height You will need to know the base or height then use Pythagoras theorem to find the base or height.

in a triangle double area and divide by base in a rectangle divide area by base

For a rectangle, the formula is: area = base x height Fill in the items you know, and solve for the remaining item.

Volume = base area x height so Base area = Volume / height. For example, if the volume is 10cm3 and the height is 2cm, 10/2=5, the base area must be 5cm2.
