students in school A = 3600
area of school A = 1800 sq.m
no. of student in A per sq. m = 3600÷ 1800 =2
student in school B = 2400
area of school B = 800 sq. m
no. of student in B per sq. m = 2400÷ 800 =3
school A is thickly populated
area of school A = 1800 sq.m
no. of student in A per sq. m = 3600÷ 1800 =2
student in school B = 2400
area of school B = 800 sq. m
no. of student in B per sq. m = 2400÷ 800 =3

School A:
Number of students = 3600
Area = 1800 m²
Find the number of students per square m:
1800 m² = 3600 students
1 m² = 3600 ÷ 1800 = 2 students
School B:
Number of students = 2400
Area = 800 m²
Find the number of students per square m:
800 m² = 2400 students
1 m² = 2400 ÷ 800 = 3 students
3 students > 2 students
⇒ School B is more populated.
Answer: School A has 2 students per square metre and School B has 3 students per square metre. School B is more populated.
