There are 5 plants x that should she plant in each row so that her 25 plants end up in a square (i.e., x plants in each of x rows)
<h3>Further explanation </h3>Maria wants to plant a small tomato garden in her yard. She bought 25 tomato plants, and she has read that ideally tomatoes are planted in a square grid to help them pollinate each other, as shown in the picture below.
How many plants x should she plant in each row so that her 25 plants end up in a square (i.e., x plants in each of x rows)? Express your answer as an integer.
If the gardener has x plants in each of her x rows, then the total number of plants will be .
Since there are 25 total plants, the correct value of x will satisfy the equation
By taking the square root of both sides and note that 25 has both a positive and a negative square root because you can't have a negative number of plants, hence you only want the positive square root:
You can solve this part simply by simple arithmetic.
