Answer:
Area is Length x Width. So 16.47 = 6.1 x X. To find out was X is, we divide each side by 6.1, to find out that 2.7 = X
For the Perimeter (aka P) you need to add all of the sides. Since it is a rectangle the side that is given to us (6.1 length) we will double that value to 12.2, for the opposite side. In finding the Area we found that X is 2.7, which doubles to 5.2. Add these two values together equals 17.4, which is the Perimeter.
