Calculate the area of triangles, squares, rectangles, octagons, circles and ellipses. Inputs and results are in any available area unit. For results, select the row and choose an alternative unit type.

- Base: Width of the bottom of the triangle

- Height: Height of the triangle from base to point

- Side: Length of one side of the square

- Length: Length of one side of a rectangle

- Width: Length of the other side of a rectangle

- Sides: number of sides where all sides are the same length

- Length: length of one edge of the regular polygon

- Radius: Radius of the circle, length from one edge to the opposite

- Short Axis Radius: Radius, length from one edge to the other, of the shorter side

- Long Axis Radius: Radius, length from one edge to the other, of the longer side

The room is 5'6" by 14'3". How many square feet is the room?

In the Rectangle section:

- Length: 5ft 6in

- Width: 14ft 3in

The area of the room is 78.38ft². If the result is not in square feet, select the Rectangle's Area row and choose ft².
