in a farm there are 600 mango trees. the number of trees in each row is 10 less than twice the number of rows. does each row hav

The area of the farm is the number of trees on it.

Each row of the farm does not have 50 trees

Let

$x \to$ number of rows

$y \to$ number of trees in each row

So, we have:

$y = 2x - 10$ --- twice less than the number of rows

The area of the farm is:

$Area = x \times y$

Where

$Area = 600$ --- the number of trees

So, we have:

$x \times y = 600$

Substitute $y = 2x - 10$

$x \times (2x - 10) = 600$

Substitute 50 for x

$50 \times (2 \times 50 - 10) = 600$

$50 \times (100 - 10) = 600$

$50 \times 90 = 600$

$4500 = 600$

The above equation is not true.

This means that, each row does not have 50 trees
