How to find BD in this case?

If we don't have the right angle also..... can we able to find the area of a plot with different measurements...please answer me

Ok this is more of a guess, but since we know it is a quadrilateral, we can assume there is at least one triangle that can be formed and since we can see that AB and BC are just 16 times 4 (AB) and 16 times 3 (BC) we can notice that it is a 3-4-5 triangle giving us that it is indeed a right triangle. This also help us find AC=80 as it is just 16*5. From there it is just heron's formula and add the two areas of the triangle together.

How to calculate the area of an irregular quadrilateral which has no right angle ? Assuming we have only all the side's length but no diameter.

Very important question. Here is a video on finding area of irregular shapes: kzread.info/dash/bejne/o3iFxsOxXcuTqZs.html Thanks

But.... any way nice explanations

how to find area if there is no right angle..ABC and side lengths AB = 64, BC = 48, CD = 50 and DA = 50..

How do you get A-C i.e 80

Pythagorean Theorem, since this is the hypotenuse. Thanks

Then how to find area of an irregular quadrilateral with same side of two angles are equal to 90 degree??

I mean adjacent angles

The isosceles triangle, dividing 80 by 2, gives two right triangles :50, 40, 30, right? Só, 80x30/2=40x30=1200. Easy than Heron's :)

correct, here is two right angle triangle so same formula can be applied in both part of triangle but result will vary.The problem will be when angle between side is unknown therefore cosine formula is more suitable to calculate such type of Area. In my view this method is not appropriate.

Sir, I need to find out area of a quadrilateral whose all 4 sides are given but none of the angles is known. Can u help please? If yes and you plan to respond to this query through a video then pls do reply to this comment because that'll notify me to check your video.
