The number on the bottom of a water bottle, usually inside a triangle, is a code that identifies the specific kind of plastic the bottle is made of.

The area of ANY triangle can be found using the formula: Area = Base of triangle * (1/2) * Height of triangle The height of a triangle is measured from the "bottom", or base of the triangle straight up to the top "corner". This measurement is inside the triangle. For example: An equilateral triangle has all 3 sides the same. (See the word equal?) Using your numbers, plug them into the formula and figure out what the area of your triangle is.
