Area is 2-dimensional like a carpet or an area rug. Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is:. However, the lateral sides of a parallelogram are not perpendicular to the base. Thus, a dotted line is drawn to represent the height. Let's look at some examples involving the area of a parallelogram.

Find the area of a parallelogram with a base of 8 feet and a height of 3 feet. Find the area of a parallelogram with a base of 4 meters and a height of 9 meters. The area of a parallelogram is 64 square inches and the height is 16 inches. Find the base.

### Vectors - area of parallelogram

Thread starter sderosa Start date Mar 17, Tags area parallelogram vectors. JavaScript is disabled. For a better experience, please enable JavaScript in your browser before proceeding. Oct 80 0. Find an area of a parallelogram determined by the points P 7,-5,5Q -5,10,10R -8,8,-4 and S ,23,1.

I have PQ and RS are parallel. I know I need to use the cross product. Any assistance on what to do next???? I would actually compute PR and SQ.

You want to use the cross product of two non-parallel outer sides the area is the magnitude of said cross product. Because PS and RQ are not parallel or anti-parallel, you know that they are diagonals, and hence not so useful you might be able to use them, but I'm not entirely sure how. Reactions: sderosa Plato MHF Helper. Aug 22, 8, Reactions: Ackbeet. The objective is to find the area of the parallelogram determined by the folowing points: P 7,-5,5Q -5,10,10R -8,8,-4 and S ,23,1 Basically I just need to solve the following: The area is PQ x PS????

We will continue to give you accurate and timely information throughout the crisis, and we will deliver on our mission — to help everyone in the world learn how to do anything — no matter what. Thank you to our community and to all of our readers who are working to aid others in this time of crisis, and to all of those who are making personal sacrifices for the good of their communities.

We will get through this together. Updated: February 20, References. A parallelogram is defined as a simple quadrilateral with two pairs of parallel sides. If you need to find the area of a parallelogram, it's easily done with a simple formula. For example, if you were trying to find the area of a parallelogram that has a length of 10 and a height of 5, you'd multiply 10 by 5 and get Therefore, the area of the parallelogram is To see more examples of how to find the area of a parallelogram, keep reading!

We should note that the cross product requires both of the vectors to be three dimensional vectors.

Also, before getting into how to compute these we should point out a major difference between dot products and cross products. The result of a dot product is a number and the result of a cross product is a vector! Be careful not to confuse the two. This is not an easy formula to remember. There are two ways to derive this formula.

Both of them use the fact that the cross product is really the determinant of a 3x3 matrix. The notation for the determinant is as follows.

The first row is the standard basis vectors and must appear in the order given here. The first method uses the Method of Cofactors. Here is the formula.

This formula is not as difficult to remember as it might at first appear to be. First, the terms alternate in sign and notice that the 2x2 is missing the column below the standard basis vector that multiplies it as well as the row of standard basis vectors. This method says to take the determinant as listed above and then copy the first two columns onto the end as shown below.

We now have three diagonals that move from left to right and three diagonals that move from right to left. We multiply along each diagonal and add those that move from left to right and subtract those that move from right to left. This is best seen in an example. Notice that switching the order of the vectors in the cross product simply changed all the signs in the result.

Note as well that this means that the two cross products will point in exactly opposite directions since they only differ by a sign. There is also a geometric interpretation of the cross product. There should be a natural question at this point. First, as this figure implies, the cross product is orthogonal to both of the original vectors. The one way that we know to get an orthogonal vector is to take a cross product. So, if we could find two vectors that we knew were in the plane and took the cross product of these two vectors we know that the cross product would be orthogonal to both the vectors.

However, since both the vectors are in the plane the cross product would then also be orthogonal to the plane. So, we need two vectors that are in the plane.

This is where the points come into the problem. Since all three points lie in the plane any vector between them must also be in the plane. There are many ways to get two vectors between these points.
