The perimeter formula here is P = 2W + 2L.
In this situation P = 32 ft = 2(3W-4) + 2W, or 32 ft = 6W - 8 + 2W, or
32 ft = 8W - 8.
Solve this for W by adding 8 to both sides of the equation:
40 ft = 8W. Then W = 5 ft, and L = 3(5 ft) - 4 ft = 11 ft.
Note that P = 2(5 ft) + 2(11 ft) comes out to (10 + 22) ft, or 32 ft, as was given.
Answer:
0+7i
Step-by-step explanation:
The real part of the expression ('a') is zero. We have shown that, so it will be in the required form. Ordinarily, 0 would not be shown when writing this number.

We have taken the question to mean the principal square root. -7i is also a root of -49.
