The Slab Area and Perimeter calculator computes the surface area and perimeter of a rectangular slab.
INSTRUCTIONS: Choose units and enter the following:
- (L) Slab Length
- (w) Slab Width
Slab Area and Perimeter (AnP): The surface area of the slab is returned in square feet (ft2) and perimeter in feet (ft). However, these can be automatically converted to compatible units via the pull-down menu.
The Math / Science
The formulas for slab area and perimeter are:
A = L⋅W
P = 2⋅L + 2⋅W
where:
- A = Surface Area of Slab
- P = Perimeter of Slab
- L = Length of Slab
- W = Width of Slab
