Answer:
length = 13 inches
Step-by-step explanation:
let the length be x
hence, the width = x-9
perimeter = 2(x+x-9) = 34
2(2x-9) = 34
4x- 18 = 34
4x = 52
x = 13
The ratio is 132:89.
If you'd like a ratio simplified, just divide like you would a fraction.
Unfortunately, 89 is a prime number, so your ratio stays the way it is.
Therefore your ratio is 132:89

Step-by-step explanation:
As we all know, i is same as root of -1
let us expand what we have;
(1 + i)^2
= 1(1 + i) + i(1 + i)
= 1 + i + i + i^2
as i is square root of -1, the square of the square root of -1 is -1
Thus, we have
1 + 2i - 1
= 2i
