The look of square waves is impressive, but they're extremely dangerous, even in small swell conditions. When two opposing swells collide, a unique pattern emerges. In other words, square waves result from the intersection of two seas, also known as cross-sea or grid waves.Ī weather pattern in the region causes the waves to form at different angles. Instead, they're the result of the way the water is moving. However, square waves do not result from any circumstance that is taking place below the water. You can easily spot the strange pattern by climbing to the top of a lighthouse or cliff or flying a drone over the area. Looking at these waves from above, it seems like there's an underwater grid forming square-shaped ripples. The phenomenon is rare yet extremely dangerous. However, in some regions of the world, you may notice the creation of a chessboard-like pattern on the surface of the water. Most waves reach the shore and break horizontally and parallel to the coastline.

20 plus 10 is 30 square units once again.Have you ever spotted a quadrilateral-shaped wave pattern in the ocean? If so, you've witnessed square waves. And then, this would'veīeen 1/2 times 4 is 2, times 5 is 10.

6 times 5 is going to beĮqual to 30 square units. Well, what's that going to be? 8 plus 4 is 12. You could view this as base 1 and base 2, you multiply that times the height and you have the area And so, another way youĬould think about it is the average of the length This could be rewritten as 1/2, 1/2 times 8 plus 4, 8 plus 4. We could express this as well if we were to factor And obviously, youĬould just evaluate this or we could see some The other base, times 4 times that same height, times 5. This base right over here which is 8, times the height, which is 5, plus 1/2 times this side, you could do that as That the area of the entire thing is going to be 1/2 times And we could evaluate each of these, or we could just add them together. And the area of this one over here is going to be 1/2 times the base, which is 4 times the height, which is 5. So the area of this one right over here is gonna be 1/2 times 8 times 5.

So that's my fairly big hint to you, if you know how to find Which is the same thing as from here to right over here, we know that this is 5.

Over here, this height, we notice this is a right angle. So the base is 4, and then the height is going to be 5. And then, this triangle over here if you were to take it outĪnd reorient it a little bit it could look like this, where the base is 4, and the triangle looks something like, looks something like this. Triangle right over here I could take it out and reorient it, so it looks something like this, where the base has length 8, and then the height right So if I were to draw a line like this it now divides the quadrilateral What if we were to take this quadrilateral and divide it into two triangles? So let me do this in a color Now, if you had a littleīit of trouble with that I'll give you a hint. You can see that theyīoth form right angles with this dotted line. And we know that this side and this side that they're parallel to each other. To try to do in this video is find the area of this figure.
