you find the area by multiplying the two together;
to make solving it easier convert the whole numbers into the fraction
5 and 2/5 would be 27/5 because you add 5 which is 25/5
9 and 2/10 would be 92/10 because you add 9 which is 90/10
so now you have 27/5 * 92/10
multiply the numerators: 27*92= 2484
multiply the denominators: 5*10=50
2484/50 or 49.68
