To find this the first step we do is multiply the length by the height (20.2 x 14.3) to get 288.86.  Now there are 2 sides just the same so together it would be 577.72.  Next is width times height.  9.1 times 14.3 to get 130.13 then times that by 2 to get 260.26.  So far we have this 577.72 + 260.26 + (length times width).  20.2 times 9.1 is 183.82 then times that by 2 to get 367.64.  Now we add all of them to get 1205.62 cm^2.  The surface area of the right rectangular prism is 1,205.62 cm^2.  If this is wrong please let me know so I can research more on the subject.  Thanks :)

Can dilations be used to form scale copies of a figure?
Inessa [10]

Answer:

sometimes

Step-by-step explanation:

There are several ways that dilation is used in real life. Here are several:

In graphic design. I actually do some graphic design, and I use dilation a lot. It is common to dilate photos to fit the space that you want it to fit.

In police work and crime investigation. Detectives and police dilate photos to see smaller details and evidence.

In architecture. It is normal for architects to make a prototype of their design or building. In order to make the building true to the prototype, they must dilate the scale and measurements.

In the doctor's office. Dilation is used in eye exams so that the eye doctor can view the patient's eye better. After a while it will slowly reduce in size and return back to normal.
