Answer:
<em>BC = 27</em>
Step-by-step explanation:
The point B is the midpoint of AC
=> AB = BC
=> 4x - 5 = 11 + 2x
Let's calculate x to work out BC
Transferring the components containing x to the left side, and other components to the right side:
=> 4x - 2x = 11 + 5
Simplifying both sides:
=> 2x = 16
=> x = 8
Working out BC:
=> BC = 11 + 2x = 11 + 2(8) = 11 + 16 = 27

Answer: 200cm
Step-by-step explanation:
The center Planck is a square of length 8cm.
The 4 next planks are of 16 cm each
And the next 4 Planks are of 32 cm each.
8 + 4(8×2) + 4(8×4)
8 + 4(16) + 4(32)
8 + 64 + 128
200 cm
Length of the original plank is 200cm
