Yes.
You can do the easy bits first. Thus, to calculate 7*5*2, instead of doing 35*2 = 70, you can calculate 7*10 = 70. By itself, the associative property is not as useful as it is in combination with the commutative and distributive properties.
None whatsoever. You might find the distributive property useful when trying to calculate 39*74. Of course, if you are familiar with the 39 times table or the 74 times table, the distributive property is a complete waste of time! But somehow I doubt that level of arithmetic competence.
The distributive property breaks down the equation to make it more simple to do. It is often used for mental math. An example is (12x56). (10x50=500)+(2x6=12) then, (500+12=512).
If you're talkin about the distributive property, here's an example of how to use it: 5(x + 4) You do 5*x= 5x and 5*4= 20 and you get 5x + 20 Get it? Hope could help :)
Yes.
It is not. You simply multiply length x width.
The distributive property is simple. What I do is think of a double rainbow... 5(3+2) = This will be simple. 5 times 3 is fifteen, 5 times 2 is 10. Now that you know about the double rainbow trick, visit math is fun for help with the distributive property.
Yes. The distributive property of multiplication over addition may help.

The multiplicative property, probably.
the property says that a+b+c is the same as a+c+b and it is the commutative property of addition.
