You don't have enough information. But if you have the base and the area, you can solve the equation for the area of the triangle for the height.
14.667 It would be proportional to the base of the first triangle. Find it by setting up a proportion: 18/22 = 12/x Cross multiply and solve for x. 18x = 264 x = about 14.67 cm
If it is a right triangle, use the Pythagorean theorem. If it is iscossolese or scalene, draw line down middle, use pythagorean theorem to solve for missing side.
Area = (1/2) x base x height , so solve this for height; height = 2 x Area / base height = (2)(81)/(9) = 18
The idea is to use the equation for the area of a triangle, replace the variables you know (in this case, area and base), and solve the resulting equation for that which you don't know (in this case, the height).
Area of a triangle = (1/2)(base)(height)
set up a proportion. cross multiply. solve
Base times height divided by 2
I could solve this if I knew what kind of triangle this was. Equilateral, Right: 30, 60, 90?

a=1/2bh; plug in what you knwo for the area and the height and then solve
Remember that in a triangle: (Base x Height) / 2 = Area In your question: (4 x Height) / 2 = 16 Now just solve for Height: (4 x Height) = 16 x 2 = 32 Height = 32 / 4 = 8 So your answer is 8 units.
There cannot be a "proportion of something": proportion is a relationship between two things, and how you solve it depends on whether they (or their transformations) are in direct proportion or inverse proportion.

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).
If it is a right triangle, use the Pythagorean theorem. If it is iscossolese or scalene, draw line down middle, use pythagorean theorem to solve for missing side.
There are many formulas to find the area of a triangle although the most common is;A=1/2bh, where b=base and h=height
