Question

Under Clean and Green school project, a school planted 6200 plants in the school. School

wanted to plant in such a way that each row contains as many plants as the number of rows.

On checking they found that the number of rows and the number of plants are not equal. What is

the least number that should be added to 6200 to make it a perfect square? Find the number of

rows and the number of plants in each row.​

Answer 1

Answer:

if it is added 200 it will perfect square

Answer 2

Number that should be added = 200 and rows and the number of plants in each row = 80

Given:

• Under Clean and Green school project, a school planted 6200 plants in the school.
• Plant in such a way that each row contains as many plants as the number of rows.

To find:

• The least number that should be added to 6200 to make it a perfect square.
• Rows and the number of plants in each row.

Explanation:

• Plant in such a way that each row contains as many plants as the number of rows.
• Hence number of rows is equal to number of column So the number of plant should be perfect square.
• So after 6200 the nearest perfect square is 6400 which is grater than 200 from 6200.
• So we must add 200 to get equal number of rows and to number of column.
• No of row = $\sqrt{6400}$ = 80
