P = 2(l + w)
w = l/2
Plug in 'l/2' for 'w' in the equation with '66':
66 = 2(l + l/2)
66 = 2l + 2l/2
66 = 2l + l
66 = 3l
22 = l
So the length is 22.
Now plug this in to find the width.
66 = 2(22 + w)
66 = 44 + 2w
22 = 2w
11 = w
So the width is 11, and the length is 22.
Part B seems to be missing, but I think I have enough information to be able to answer.
Let's say we had two numbers x and y. Let x be rational and y be irrational.
If x is some nonzero number, then x*y is irrational. The proof for this is a bit lengthy so I'll leave it out.
For instance,
x = 2 is rational, y = sqrt(3) is irrational, x*y = 2*sqrt(3) is irrational.
------------------
If we made x = 0, then
x*y = 0*y = 0
This is true for any value of y that we want. The y value doesnt even have to be irrational. It can be any real number.
------------------
So the distinction is that if x = 0, then x*y = 0 is rational since 0 is rational. Otherwise, x*y is irrational.
