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)

Further explanation

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 x^2 .

Since there are 25 total plants, the correct value of x will satisfy the equation x^2 = 25

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.

x^2 = 25, so x = 5,

There should be $\boxed{5{\text{ plants }}x}$ in each row so that there are 25 plants in the square.

Further Explanation:

The formula of area of square can be expressed as follows,

$\boxed{Area = \left( s \right) \times \left( s\right)}$

The formula of perimeter of the rectangle can be expressed as follows,

$\boxed{{\text{Perimeter}} = 4 \times s}$

Here, s represents the side of square.

Given:

There should be 25 plants end up in a square.

Explanation:

Consider the number of rows as x.

The number of rows can be expressed as follows,

$\begin{aligned}{x^2} &= 25\\x &= \sqrt {25}\\x &= 5\\\end{aligned}$

There should be $\boxed{5{\text{ plants }}x}$ in each row so that there are 25 plants in the square.
