Answer:
I'm most certain it is 8.89
Step-by-step explanation:
the formula:
((y2 - y1) / y1)*100 = your percentage change
(where y1=start value and y2=end value)
((49.000 - 45.000) / 45.000) * 100 = 8.89 %
Answer:
8% increase
Step-by-step explanation:
The length after the increase:
30 x 1.1 = 33cm
The width after the increase:
20 x 1.05 = 21cm
New perimeter:
2(33 + 21) = 108 cm^2
Old perimeter:
2(30 + 20) = 100 cm^2
Percentage increase of area:
108 / 100 = 1.08 = 8% increase
