Question

How is the formula for the area of a parallelogram ABCD derived?

Answer 1

`color(white)(xx)A=ah`
or
`color(white)(xx)A=a*bsinalpha`

Explanation:

Let side lengths of parallelogram be `a`, `b`, height be `h`, and interior angle `alpha`. Then
`color(white)(xx)A=ah`
or
`color(white)(xx)A=a*bsinalpha`
