`A = L * W `

Enter a value for all fields

The **Area of a Concrete Slab** calculator computes the surface area of a rectangular slab.

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

- (
**L**) Slab Length - (
**w**) Slab Width

**Surface Area (A):** The surface area of the slab is returned in square feet (ft^{2}). However, this can be automatically converted into other area units (e.g. square meters) via the pull-down menu.

The formula for slab area is:

A = L⋅W

where:

- A = Surface Area of Slab
- L = Length of Slab
- W = Width of Slab
