A rectangular garden is 6 feet long and 4 feet wide. A second rectangular garden has dimensions that are double the dimensions of the first garden. What is the percent of change in perimeter from the first garden to the second garden?
Answers
perimiter
P=2(L+W)
if we have
L=6
W=4
P=2(6+4)
P=2(10)
P=20
original is 20
if both are doubled
6*2=12
4*2=8
P=2(12+8)
P=2(20)
P=40
from original to new is
from 20 to 40
what is percent change?
find chnage
new-original=change
40-20=20
percent change=change/original
20/20=1=100%
answer is 100%

the figure shows that the second garden has a circumference twice . We must , however, prove.
Denote the sides of the first garden - a rectangle letters a and b
circuit garden
C₁ = 2a + 2b = 2*(a+b)
The sides of the second garden also denoted with the letters a and b . We calculate the circuit
C₂ = 2*2a + 2*2b = 4a + 4b = 4*(a+b)
2 = 2*100%=200%
200% -100% = 100%
Answer : The ratio of the second garden to the first ( ratio ) is 2 . Circuit increased by 100 %

Answers
Whenever we are given with the diameter of any such figure ,
to find the radius , we divide the diameter by 2.
We know that
Diameter = 2 * radius
or
Radius = Diameter /2
,
In the question it says the in first step that
the radius should be found by multiplying the diameter by 2
, this is the first error
It should be that
the radius should be found by dividing the diameter by 2

Question:
Given f(x) = 3x-1 and g(x)=2x-3, for which value of x does g(x) = f(2)?
Answer:
The value of x is 4 for g(x) = f(2)
Solution:
Given that,
We have to find the value of "x" such that g(x) = f(2)
Let us first find f(2)
Substitute x = 2 in f(x) function
Thus f(2) is 5
Now find: g(x) = f(2)
Equate given function of g(x) and f(2) which is found to be 5
Thus for x = 4 , we get g(x) = f(2)
