Answer:

307

Step-by-step explanation:

You get the area from every side like so-

12 * 11= 132

12 * 5= 60

12 * 5=60

5 * 11 = 60

You add them all up to get 307.

I don't know if that's a 5 or a 3 on the side there but I can edit this if it's a different number.

A different way to solve a mixed-number addition problem
kompoz [17]

Answer:

Step-by-step explanation:

example :

2 1/4  + 3 1/2

you can either turn them to improper fractions, find the common denominator, and then add them and then convert that answer to a mixed number

2 1/4 + 3 1/2 = 9/4 + 7/2 = 9/4 + 14/4 = 23/4 = 5 3/4

OR

separate them....add the whole numbers, then the fractions

2 1/4 + 3 1/2 .......2 + 3 = 5.....1/4 + 1/2 = 1/4 + 2/4 = 3/4.....now put them back together and u get : 5 3/4

Step-by-step explanation:

Since we have given that

Number of students = 16

Number of desks = 16

a)  How many days must pass before the class must repeat a seating arrangement?

16!=2092278989

If the number of rows = 4
