So the scale is 3/4 cm for every 6 meters
So if you have 8 cm, we want to find the dimension of the actual wall
convert cm to meters
0.75 cm = 0.0075 meters
8 cm = 0.08 meters

Cross Multiply
0.0075x = 0.48
x = 64 meters
Answer:
Possible C:
(1 , 1 + 3sqrt(3))
(1 , 1 - 3sqrt(3))
Step-by-step explanation:
AB = 6 units
Midpoint of AB is (1,1)
C would be at x = 1
So, (1,y)
(y-1)² + (1+2)² = 6²
(y-1)² = 36 - 9
(y-1)² = 27
y - 1 = 3sqrt(3)
y - 1 = -3sqrt(3)
y = 1 + 3sqrt(3)
y = 1 - 3sqrt(3)
1.065. The 5 is the nearest thousandth
