Answer:
40ft
Step-by-step explanation:
Add up all four sides of your rectangle:
15ft + 15ft +5ft + 5ft = 40ft
You can find the other 5ft (the side that is missing) if you notice that the smaller sections are squares.
I am not too sure whether there were options, but one way to approach this is to fill it with "multiplication" and "addition" - the distributive property combines addition and multiplication to make multiplying whole numbers simpler.
The gain is that you don't have to make one difficult multiplication, but a couple of simpler ones and then you can add them up.
Answer:
A)(Always)Rational
B)(Always)Rational
C)(Sometimes)Rational
This is because Square roots are generally irrational(like the 
) and the product and difference of rational numbers should always be rational!
Hope this helps!
Sorry, cannot explain more ... :(

Answer:
LCM: 1,800
GCF: 150
Step-by-step explanation:
150:600 = 150 / 600 = 0.25 (that's pretty much what a ratio is, just a fraction or part of a whole.)
150 is the greatest common number that will factor into all three, and the least/smallest number they all multiply into is 1,800
