Question

An orchard contains $5$ rows of orange trees with $7$ trees in each rows. The number of rows of trees that needs to be planted to make a total of $49$ oranges trees in the orchard is .

Answer 1

Rows $=5$
Columns $=7$
Total no. of trees $=5\times 7=35$
No. of trees that needs to be added to make a total of 49 trees $=49-35=14$
Each row contains 7 trees.
New rows required $=14÷7=2$
$14$ more trees will require $2$ more rows that needs to be planted.
