A gardener wants to plant 122500 trees in his field in such a way that the number of trees in a row is equal to the number of rows. How many trees will he plant in each row?

Given that the gardener wants the number of trees in each raw to be equal to the number of rows, then let the number of in each row be x this means that the number of rows will be x.

Thus the total number of trees will be:

Total = (number of rows) * (number of trees in each row)

hence:

122500=x*x

122500=x²

hence

x=√122500

x=350

thus the number of rows will be 350 and the number of trees in each row will be 350
