A=LxW, but first you should convert the mixed fractions to improper fractions:
7/3 x 27/5 = 189/15 = 12 6/10 = 12 3/5 square inches

P = L+L+W+W here I would convert to improper fractions, but then you need to find a common denominator.
P = 7/3 + 7/3 + 27/5 + 27/5 = 14/3 + 54/5 = 70/15 + 162/15 = 232/15 = 15 7/15 inches

Area: If you multiply 2 1/3 by 5 2/5, you get an answer of about: 12.6, which means the area is about: 12.6in. squared.
Perimeter: If you add 2 1/3+ 2 1/3+ 5 2/5+ 5 2/5 you get an answer of about: 15.47. So, the perimeter is about 15.47in.

Note: If you aren't allowed to use a calculator on this test, you should probably multiply the numbers yourself so you get show the work and get the answer in a fraction, which is probably what they want. If you are allowed to use calculators, all the information you need is right here.
