Answer:
9 students in each row
Step-by-step explanation:
Given : 54 students, arranged in 6 rows (with equal students), singing 7 songs.
No of students in one row x No of rows = Total students
So, No of students in one row = Total students / No of rows
No of students in each row = 54 / 6 = 9
3.5
11.5 - 2.5 = 9
9 - 5.5 = 3.5
and scalene triange means none of the 3 sides are equal...
3.5 does not equal 5.5 or 2.5
