Answer:
0.5328
Step-by-step explanation:
µ = 50
σ = 8
We are supposed to find the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees

Formula : 
at x = 46


Refer the z table for p value
p value = 0.3085
at x = 58


Refer the z table for p value
p value = 0.8413

Hence the probability that the high temperature on October 31 in a randomly chosen year will be between 46 degrees and 58 degrees is 0.5328
L=w+2 and 2w+2l=40
Substitute length for w+2 in perimeter formula.
2w+2(w+2)=40
2w+2w+4=40
4w+4=40
4w=36
w=9
l=w+2
l=9+2
l=11
a=lw=11*9=99 meters
