First is B, since 1 and 3 are corresponding angles, they must be equal
Next is I, 3 and 5 must be equal since they are vertically opposite
Last is transitive property
Since 1 = 3 and 3 = 5, then 1 must equal 5
X=0 y=-2
y=0 x=4
The shortest distance has to be the perp bisector from origin to the midpoint of the line.
midpoint =(2,-1) and distance from the (0,0) origin is sqrt(5) hence, sqrt(5).
Answer: The area of the cross section is 2 cm^2.
If I am understanding your problem correctly, we are just looking for the area of the grey rectangle, which is the cross section.
The length and width of this gray rectangle are already given to us. The are 1 and 2. Just multiply them to get the area.
1 x 2 = 2 cm^2
