No it can't, because:
P= 2(l+w)
therefore if x=20
P=2(20+11)
P=62 does not equal to 64.
x must be 21 for the equation to be true.

Simple.
Plug in what you known into the equation.
150 = 6e^2.
Divide 150 by 6 to isolate the variable.
150/6 = e^2
25 = e^2
take the square root of 25
5 = e

Hope this helps!
