Answer:

Step-by-step explanation:

Here,

Let x be the number of trees in each row

And y be the number of trees in each column.

As per the question,

xy=200 .......(1)

And

x = y +10 .........(2)

Substituting (2) in (1)

We get,

xy=200

(y+10)y=200

y²+10y=200

By factorisation method,

y²+10y=200

y²+10y-200=0

y²+20y-10y-200=0

y(y+20)-10(y+20)=0

(y-10)(y+20)=0

y-10=0 or y+20=0

y = +10 or y = -20

Negative number will not be considered.

So,

When y=10

x=y+10

=10+10

x=20

The number of trees in each row is 20trees.

Done!!
