which calculates the area of a triangle given height from column B and base from column C.

where b represents the base of the triangle, and h represents the height, measured at right angles to the base. In Excel, the same formula can be represented like this: So, for example, to calculate the area of a triangle with a base of 4 and a height of 3:  In the example shown, the goal is to calculate the area for eleven triangles with base given in column B and height given in column C. The formula in D5 is: As this formula is copied down the table, it calculates a different area at each new row. Note: The parentheses in this formula are optional and for readability only. In Excel’s order of operations, multiplication will occur before division, so the parentheses are unnecessary.
