The Perimeter of a Quadrilateral calculator computes the semi-perimeter of a quadrilateral based on the length of the four sides.

INSTRUCTIONS: Choose units and enter the following:

• (A) Length of side A.
• (B) Length of side B.
• (C) Length of side C.
• (D) Length of side D.

Perimeter (p): The calculator returns the semi-perimeter in meters. However, this can be automatically converted to compatible units via the pull-down menu.

The Math / Science

The formula for the perimeter of a quadrilateral is:

     `p = a+b+c+d`

where:

• p = quadrilateral perimeters
• a = length of side a
• b= length of side b
• c = length of side c
• d = length of side d
