the side of a square 20 centimeters each is decreased by 2 cm each. what is the percentage decrease in the length of a side of the square?
Answer (1)
The percentage decrease in the length of a side is 10%.The formula for finding the percentage decrease is: [tex]Percentage Decrease = (\frac{Original Value - New Value}{Original Value})[/tex] × [tex]100[/tex]Using the formula above, let's replace them with the values in the Math problem. Each side of a square is 20cm and is decreased by 2cm each.[tex]Percentage Decrease = (\frac{20 - (20-2)}{20})[/tex] ×[tex]100[/tex][tex]Percentage Decrease = (\frac{20 - 18}{20} )[/tex]×[tex]100[/tex][tex]Percentage Decrease = (\frac{2}{20})[/tex]×[tex]100[/tex][tex]Percentage Decrease = 0.1[/tex] ×[tex]100[/tex][tex]Percentage Decrease = 10%[/tex]%
