Here is your answer
Let the widht of rectangle be x metres
Then, its length= x+2 metres
Perimeter= 2 (l+b)
=> 34 = 2 (x+2 + x)
=> 34/2 = 2x+2
=> 17= 2x+2
=> 2x= 17-2
=> x = 15/2 metres
Width= 15/2 metres
Length= 15/2 + 2
= 19/2 metres

Answer:
60 students passed, and 75 appeared in examination.
Step-by-step explanation:
Let's say s is the total number of students and p is the number of students who passed.
80% of the students passed, so:
0.8 s = p
If there were 10 less passers, and 15 less students (5 less failures), then the ratio of passers to failures would be 5/1.
(p − 10) / (s − p − 5) = 5 / 1
Simplify the second equation:
p − 10 = 5 (s − p − 5)
p − 10 = 5s − 5p − 25
6p = 5s − 15
Substitute the first equation.
6 (0.8 s) = 5s − 15
4.8 s = 5s − 15
0.2 s = 15
s = 75
p = 0.8 s
p = 60
60 students passed, and 75 appeared in examination.
