Square needs to have all equal sides and length and width are the same.
So sqrt the area.
sqrt 121 = 11
11 feet is the length of one side, square has 4.
So
11 * 4 = 44
The perimeter of a square (whose area is 121 feet) is 44 feet.
Answer:
D. 7 +11i
Step-by-step explanation:
In many situations, you can treat "i" as though it were a variable. Collect terms in the usual way.
(2 +8i) -(-5-3i) = 2 +8i +5 +3i = (2+5) +(8+3)i
= 7 +11i
