The area of a 2D form is the amount of space within its perimeter. The correct option is C.
What is an area?
The area of a 2D form is the amount of space within its perimeter. It is measured in square units such as cm2, m2, and so on. To find the area of a square formula or another quadrilateral, multiply its length by its width.
The suface area of the complete prism
= 2x² + 4xy
= 2x² + 4x(2x)
= 2x² + 8x²
= 10 x²
The surface area of the half prism
= 2x² + 4x(y/2)
= 2x² + 4x(2x/2)
= 6x²
Thus, The surface area of each piece is equal to the sum of half the surface area of the original block plus the area of the face created by the cut.
Hence, the correct option is C.
