Answer:
8%
Step-by-step explanation:
Length = 30 cm
It increases by 10 %
The increase is 30*.10 = 3
New length = old length + increase
30+3
33 cm
Width =20
It increases by 5%
The increase is 20 *.05 = 1
New width = old width + increase
=20+1
21
Old perimeter = 2(l+w) = 2(30+20) = 2(50) = 100
New perimeter = 2(l+2) = 2(33+21) =2(54) = 108
Percent increase = (new - old)/old * 100%
= (108-100)/100 * 100%
= 8/100*100%
=8%

Answer:
Y = 10.25 or 10.247
Step-by-step explanation:
Alright So use the Formula A^2 + B^2 = C^2
You have one leg and the hypotenuse so first you are going to find 19 ^2 = 361.
Next, you need to find 16^2 = 256.
Last but not least, you subtract the leg from the hypotenuse, which equals 361-256=105
Finally, you take 105 and find its square root.
And depending on how far you round it down, your answer would be 10.25(that is in tenths), or 10.247(which is rounded to hundredths)
Hope this helps!
