Question

In school all children were made to stand in a square formation.Out of left 3050 children,25 were left after forming the square.How many children are there in each row?

Answer 1

Total number of student = 3050

number of children left =25

3050−25=3025

Let the no of rows =x

x×x=3025

x2=3025

x=3025−−−−√

x=55

number of children in each row = 55

Hope this helps and please mark as brainliest and follow me

Answer 2

3050-25=3025.

now
Given it is in SQUARE formation
So the root of 3025 will give us the no: of rows( and also the no: of columns)

Now,
Now of Rows(or columns)=√3025=55Rows(and column's)


Hope it Helps...
