Answer:
Yes!
Step-by-step explanation:
I know this from having been a bank teller. But let's examine the math.
Any two digit number can be written as 10x + y.
Reverse the digits would give you
10y + x
Subtract to find the difference.
10x + y - (10y + x)
10x + y - 10y - x
10x - x - 10y + y
9x - 9y
9(x - y)
Yes, it has 9 as a factor, so it is a multiple of 9.

bh ( b is the base and h the perpendicular height )
here b = 14 and h = 4, hence
A = (14 × 4) = 28
