An additional to a house increases the floor area from 275m² to 300m². By what percent was the original floor area increased?
25/275 = 0.09 = 9%
Why do you divide by 25?
300 - 275 = 25
To find out the percentage increase in the original floor area, we can follow these steps:
1. Calculate the difference in floor areas: New floor area - Original floor area
Difference = 300m² - 275m² = 25m²
2. Determine the percentage increase: (Difference / Original floor area) x 100%
Percentage Increase = (25m² / 275m²) x 100%
Now, let's simplify this equation:
Percentage Increase = (25/275) x 100%
Percentage Increase = (1/11) x 100%
Percentage Increase = 9%
Therefore, the original floor area was increased by 9%.
