Answer:
35m
Step-by-step explanation:
length = 2+w
width = w
Perimeter = 2(length)+2(width)
24 = 2(2+w)+2(w) = 4+2w+2w = 4+4w
24=4+4w
4w=20
w=5
width =5
length = 2+5 = 7
Area = (length)(width) = 5(7) = 35m
Answer: a) 0.07910, b) 0.000976, c) 0.7626
Step-by-step explanation:
Since we have given that
Number of questions = 5
Number of choices = 4
P(getting correct) = 
a) the first question she gets right is the 5th question?
P(getting 4 wrongs answers and one right answer) is given by

b) she gets all of the questions right?
P(all right )= 
c) she gets at least one question right?
1-P(All of them wrong)

Hence, a) 0.07910, b) 0.000976, c) 0.7626
