if someone tells you that the land of ​​a parallelogram is 5 and the height is 2, then you can easily say that the area of ​​the parallelogram is 10 square units. But what if anyone give you the land, width and value of an angle (not height)…

I made a formula. I will say that later some other time. Think about how the formula will be…

[abrerrasik]

If the measurements of the base and width respectively are a and b and the angle between them is A, then the area will be equal to a.b.sinA
