` = "Floor Area + (Squared Bump-out)"`

Enter a value for all fields

The** Floor Area of a Room with a Squared Bump-out** calculator computes the floor area of a rectangular room with a squared (rectangular) bump-out based on the length and width of the room and bump-out.

**INSTRUCTIONS:** Choose units and enter the following:

**(L)**Length of Room**(W)**Width of Room- (
**BW**) Bump-out Width - (
**BD**) Bump-out Depth

**Total Floor Area (TA):** The calculator returns the total area in square feet. However, this can be automatically converted compatible units via the pull-down menu.

The formula for the area of a rectangular room with a squared bump-out is:

A = L ⋅ W + BD⋅BW

where:

- A = Floor Area of Room with Squared Bump-out
- L = Length of Main Room
- W = Width of Main Room
- BW = Width of Bump-out
- BD = Depth of Bump-out

- Area of Room's Floor - Area of Floor in Rectangular Room
- Area of Room's Floor with Angled Bump-out - Area of Floor in Rectangular Room with Angled Bump-out
- Area of Room's Floor with Squared Bump-out - Area of Floor in Rectangular Room with Squared Bump-out

Most rooms are simple rectangles with a length and a width. The only common departure are rooms with bump-outs. Some bump-outs are angular and taper down from an opening. Some bump-outs have squared corners. To compute the square feet of these floors are simple geometry based on the measurements of the main floor and the bump-out dimensions.

To compute the area of a floor with a different shape (e.g., circular, oval, or polygon), see the Area Calculator.
