Question

a gardener planted 1521 trees in a row such that the number of rows was equal to the number of plants in each row. find the number of rows

Answer 1

Let the no. of row be x. Then no. of plant is also x. If we multiply no. of plant and no. of row then we get total no. of plant. Multiplying we get x^2 But we know the total no. of plant i.e.1521 Therefore x^2=1521 => X=39. Hence,total no. of plant in each row is 39
