The percentage decrease in length of the board is 25%
From the given statement we can deduce the following:
- original length of the board = 24 cm
- new length after cutting 6 cm = 24 cm - 6 cm = 18 cm
The change in the length of the board is calculated as:
- Change in length = original length - new length
- Change in length = 24 cm - 18 cm
- Change in length = 6 cm
The percentage decrease in the length is calculated as;
[tex]Percentage \ decrease = \frac{change \ in \ length }{original \ length} \times 100\%\\\\Percentage \ decrease = \frac{6}{24} \times 100\%\\\\Percentage \ decrease = 25\%[/tex]
Thus, the percentage decrease in length of the board is 25%
