Answer:
The area of the resulting two-dimensional cross-section is 12 cm².
Step-by-step explanation:
The area of the cross-section of the right rectangular prism, parallel to the base, is given by the area of a rectangle:
[tex] A_{cs} = A_{r} = a*b [/tex]
Where:
[tex] A_{cs}[/tex]: is the area of the cross-section
[tex] A_{r} [/tex]: is the area of a rectangle
a: is the length of one side of the rectangle = 4 cm
b: is the length of the other side of the rectangle = 3 cm
Hence, the area of the cross-section is:
[tex] A_{cs} = a*b = 4 cm*3 cm = 12 cm^{2} [/tex]
Therefore, the area of the resulting two-dimensional cross-section is 12 cm².
I hope it helps you!
