Question

vera is creating a square flower garden with an area of 324 square feet. what is the length of one side of the garden? a 13 feet b 18 feet c 20 feet d 15 feet

Explanation:

Step1: Recall area formula for square

The area formula for a square is $A = s^2$, where $A$ is the area and $s$ is the side - length.

Step2: Solve for side - length

Given $A = 324$ square feet, we have $s=\sqrt{A}$. So $s=\sqrt{324}$.

Step3: Calculate the square root

We know that $18\times18 = 324$, so $\sqrt{324}=18$.

Answer:

B. 18 feet
