Answer:
Percent of decrease in the value is 40%.
Step-by-step explanation:
Let's find the value of y when t=1 and t=2 because need to find the decrease by percent of t increases by 1 unit.
When t=1
y==0.6
When t=2
y= =0.36
Percent of decrease = 100 % -% = 100% -60% =40%
b
58/2 = 29
w +2w+2 = 29
3w+2 =29
3w = 27
w = 27/3 = 9
width = 9
length = 2*9=18+2 = 20
20+20+9+9 = 58
Length = 20 feet
width = 9 feet
