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
Answer:
approximatly 34.18
Step-by-step explanation:
so we know that a^2 + b^2 = c^2
so knowing we are finding the hypotenuse ( longest side of the triangle ), we are solving for c!
so now lets fill in the equation:
12^2 + 32^2 = c^2
so now lets break it down
12^2=144 & 32^2= 1,024
fill in the equation: 144 + 1,024 = 1,168
now just find the square root of 1,168!
which is approximatly: 34.18!!
i really hope this helped <3
Answer:
the answer is B
Step-by-step explanation:
