The formula for area is A=L*W, so you multiply 1/3 in. By 2/5 in. Find what 1/3 times 2/5 is and then you simplify it down. Simplifying is just solving it really. If I had 10/20 the simplest form would be 1/2 because 10/20 is the same thing as 1/2. Just simplify that fraction you come up with and that will be your answer
