The perimeter of parallelogram ABCD is equal to 68 inches.

Given the following data:

  • Length of AB = 14 inches
  • Length of BC = 20 inches

How to calculate the perimeter of a parallelogram.

Mathematically, the perimeter of a parallelogram is given by this formula:

[tex]P=2(A+B)[/tex]

Note: The opposite sides of a parallelogram are always equal and as such we have:

  • AB = DC
  • AD = BC

Substituting the given parameters into the formula, we have;

[tex]P=2(14+20)\\\\P=2(34)[/tex]

P = 68 inches.
