A parallelogram can be described with either four vertices or two vectors. In this case, since we are given four vertices (A, B, C, D), we can find vectors u and v that describe the parallelogram. graphing these points will show how the vectors are related.
A=(0,0)
B=(5,2)
C=(6,4)
D=(11,6)
u=AB=[52]
u=AC=[64]
The area of a parallelogram is the magnitude of the determinant.
[u1v1u2v2]
[u1v1u2v2]=det[5624]=2012=8
Result:
8

Step 1:
First, we need to find the vectors AB and AD using the coordinates of points A, B, and D.
The vector AB is obtained by subtracting the coordinates of point A from the coordinates of point B:
AB=(50,20)=(5,2).
Similarly, the vector AD is obtained by subtracting the coordinates of point A from the coordinates of point D:
AD=(110,60)=(11,6).
Step 2:
Now, we can find the area of the parallelogram using the cross product of the vectors AB and AD. The magnitude of the cross product gives us the area of the parallelogram:
{Area}=|AB×AD|.
The cross product of two vectors in 2D can be calculated as follows:
AB×AD=(x1y2x2y1), where x1 and y1 are the components of AB and x2 and y2 are the components of AD.
Applying the formula, we have:
AB×AD=(5·611·2)=(3022)=8.
Taking the absolute value, we find that the area of the parallelogram is 8 square units.

Solution:
A=|𝐚×𝐛| where 𝐚 and 𝐛 are vectors formed by two adjacent sides of the parallelogram, and × denotes the cross product.
Let's denote the given vertices as A(0,0), B(5,2), C(6,4), and D(11,6). We need to find the vectors 𝐚 and 𝐛.
The vector 𝐚 is formed by the sides AB or DC, and the vector 𝐛 is formed by the sides BC or AD.
Using the coordinates, we can find the vectors AB and BC:
AB=xBxA,yByA=50,20=5,2
BC=xCxB,yCyB=65,42=1,2
Now, we can calculate the cross product of 𝐚 and 𝐛:
𝐚×𝐛=|𝐢𝐣𝐤520120|
Expanding the determinant, we have:
𝐚×𝐛=(2·00·2)𝐢(5·00·1)𝐣+(5·21·2)𝐤
Simplifying further, we get:
𝐚×𝐛=0𝐢0𝐣+8𝐤=0,0,8
Finally, we can find the magnitude of 𝐚×𝐛 to obtain the area of the parallelogram:
A=|𝐚×𝐛|=|0,0,8|=02+02+82=64=8
Therefore, the area of the parallelogram is 8 square units.

To find the area of a parallelogram given its vertices, we can use the formula:
Area=|x1y2x2y1+x2y3x3y2+x3y4x4y3+x4y1x1y42|
where (x1,y1), (x2,y2), (x3,y3), and (x4,y4) are the coordinates of the vertices.
For the given vertices: (0,0), (5,2), (6,4), and (11,6), we can substitute the coordinates into the formula:
Area=|(0·25·0+5·46·2+6·611·4+11·00·6)2|
Simplifying this expression, we get:
Area=|0+2012+3644+002|
Area=|02|
Therefore, the area of the parallelogram is 0 square units.
