Question

there are certain number of rows of trees in a garden the number of trees in each row is twice the numbers if the number of trees in garden is 1250.find the number of rows

Answer 1

Let the numbers of rows be x

so the numbers of trees in each row =2x

total number of trees=2x×x

1250=2x×x

2x²=1250

x²=625

x=25

there are 25 rows

Answer 2

Answer:

Number of rows in the garden = 25

Step-by-step explanation:

Let the numbers of rows of trees in the garden be x

Since, number of trees is twice the number of rows in the garden

⇒ The numbers of trees in each row =2·x

⇒ Total number of trees=2·x × x

⇒  1250 = 2·x²

⇒ 2·x² = 1250

⇒  x² = 625  

⇒ x = 25

Hence, number of rows in the garden = 25
