Answer:
Area = 105 11/12
Step-by-step explanation:
First, we need to convert the mixed numbers into fractions using the following equation:

So, 10 1/3 and 10 1/4 are equivalent to:

Then, the area of a rectangle can be calculated as:
Area = Length x Width
So, the area of a rectangle of 31/3 by 41/4 is:

Finally, 1272/12 as a mixed number is

Therefore, the area is 105 11/12
