The last number is not possible, you cannot have two decimal points in a number, and the second number cannot round to 8.3
teh first number is your only choice
Total length of the board = 2.5 meters
= (2.5 * 100) cm
= 250 cm
Let us assume the length of the first shelf = x
Then
Length of the second shelf = 2x + 18
Length of the third shelf = x - 12
Length of the fourth shelf = x + 4
Now we can easily get the equation as
x + 2x + 18 + x - 12 + x + 4 = 250
5x + 10 = 250
5x = 250 - 10
5x = 240
x = 240/5
= 48 cm
length of the second shelf = 2x + 18
= 2(48) + 18
= 96 + 18
= 114 cm
So the length of the second shelf is 114 cm.
