First, convert all mixed numbers to improper fractions. We get
6 1/3 = 19/3
4 1/4 = 17/4
5 5/8 = 45/8
----
Lets start with area.
A+=+LW
in our case it is
A+=+%2819%2F3%29%2A%2817%2F4%29
this is
A+=+323%2F12
or A ~ 19.333 or 19 1/4
----
perimeter+=+2%2A%2819%2F3%29+%2B+2%2A%2845%2F8%29
perimeter+=+%2838%2F3%29+%2B+%2890%2F8%29
perimeter+=+23+11%2F12
