I believe it is 64 cm squared
If z = a-bi, the complex conjugate of z is a + bi.
So the imaginary part is "b"
"b" is opposite of -b, so correct answer is c)
Answer:
28 cm
Step-by-step explanation:
If the shape is a square, all the sides are equal. To find the area you multiply the length by the width. Since the area is 49 centimeters, find the square root of 49 to find the length of the length and the height of the square, which is 7. To find perimeter, you add the lengths of all the sides of the square. 7+7+7+7=28.
