1. Let the Number of Plants Rows be : N
Given that Each Row Contains as many plants as the number of rows
⇒ Each Row contains 'N' number of Plants
⇒ The Total Number of Plants = Number of Rows × Number of Plants in each Row
⇒ The Total Number of Plants = N × N
Given the Total Number of Plants in the Garden = 2025
⇒ N × N = 2025
⇒ N² = 2025
⇒ N = 45
⇒ The Number of Rows = 45
⇒ The Number of Plants in each Row = 45
2. Let the Number of students in the 8th Grade be : S
Given that Each student donated as many rupees as the Number of students in the class.
⇒ Each student Donated : S rupees
⇒ Total amount donated by the students = Number of Students in the Class × S rupees
⇒ Total amount donated by the students = S × S
Given the Total amount donated to PMNRF : 2401 rupees
⇒ S × S = 2401
⇒ S² = 2401
⇒ S = 49
So the Total Number of students in the 8th Grade = 49
