# Area of a parallelogram

`=bh`

To calculate the area of a parallelogram in Excel, you can use a standard formula with Excel's multiplication operator. In the example shown, the formula in D5, copied down, is:

=B5*C5

which calculates the area of a parallelogram given the base in column B, the height in column C.

A parallelogram is a quadrilateral (4-sided) shape with two pairs of parallel sides. The opposite sides of a parallelogram are the same length, and the opposite angles have the same measure. In Euclidean geometry, the area enclosed by a parallelogram is defined by this formula: A=*bh*, where **b** stands for base and **h** stands for height.

In Excel, the same formula can be represented like this:

=b*h

So, for example, to calculate the area of a parallelogram where **b** is 5, and **h** is 4, you can use a formula like this:

=5*4 // returns 20

In the example shown, the goal is to calculate the area for eleven parallelograms using the base value in column B and the height value in column C. The formula in D5 is

=B5*C5

Because both cells are entered as relative references, as the formula is copied down the table, it calculates a different area at each new row.
