Answer: The required area of the exposed 2-dimensional shape would be 137.5 sq. inches.
Step-by-step explanation:
Given, There is a rectangular prism with a length of 12.5 in., a width of 11 in. and a height of 4 in.
If we make a horizontal slice through it, then we will have two-dimensional figure called 'rectangle' with dimensions length by width as 12.5 in. by 11 in. [As per given]
Then, the area of the exposed 2-dimensional shape = Area of the reactngle
= Length x width
[tex]=12.5\text{ in.}\times11\text{ in.}\\\\=137.5\text{ in.}^2[/tex]
Hence, the required area of the exposed 2-dimensional shape would be 137.5 sq. inches.
