Parallelogram calculator helps to find out the area, perimeter and diagonal lengths of a parallelogram in an easy way. The formula related to the area, perimeter and lengths of the diagonals are mentioned below:

Area= bh = absinθ

Perimeter = 2a+2b

Short diagonal = $\sqrt{a^{2}+b^{2}-2abcos(\theta)}$

Long diagonal = $\sqrt{a^{2}+b^{2}-2abcos(\pi -\theta )}$

Where a and b are the base length
            h is the altitude
            $\theta$ is the angle
Following steps are used to find the area, perimeter and diagonal lengths of a parallelogram.

Step1: Note down the given values from the question.

Step2: Find out the area using given equation.
Area= bh=absinθ

Step3: Perimeter of a parallelogram is given by,

Step4: Diagonal lengths are given by,
Short diagonal=$\sqrt{a^{2}+b^{2}-2abcos(\theta)}$
Long diagonal=$\sqrt{a^{2}+b^{2}-2abcos(\pi -\theta )}$
