Answer:
9 cm
Step-by-step explanation:
c^2=81
Take the square root of both sides.
The square root of c^2 is c.
The square root of 81 is 9.
c=9
Answer:
C = 9 centimeters
Step-by-step explanation:
First, look at the area of a square, which formula is c^2 or in standard format - s^2. Thus, we can say, c^2 = 81. Then, we can simplify, and put c = √81. Since 81 is a perfect square, 9 * 9 = 81. Thus the answer is 9 centimeters.
Answer:
Length of AB is 12
Step-by-step explanation:
Here, we are concerned with finding the full length of line AB, given the distance between the midpoint of the line AB and the point B itself
What this means is that, the distance of the halfway of the full length is 6
So the total distance would be twice the halfway distance
So if the halfway distance is 6, then the full distance would be 6 * 2 = 12
So the length of AB = 12
