Answer:
1200
Explanation:
Order does not matter, if we said xyz order, it would still not make a difference if it was zyx or yzx hence we use the combination formula:
nCr = n! / r! * (n - r)!
where n= total number of items
r= number of items chosen at a time
Combinations are used when the order of events do not matter in calculating the outcome.
We calculate using the formula:
(30×20×12)÷3!=1200
There are therefore 1200 ways for the three distinct items to not be in same row or column
When you graph the three lines, the first two overlap. The third is parallel to those two.
Answer:
(20x30)= 600
that's the area of rectangular plot
3ft wide sidewalk means both +3 on left and +3 on right, also both +3 up and +3 down

936-600=336 square feet
