Question

1. Sam is planning to put a square garden with an area of 225 square feet in her back yard. What will be the perimeter of the garden?

Answer 1

60 feet

Step-by-step explanation

We have that the area of the square garden is 225 square feet.

To find the perimeter, we have to first find the length of the sides of the garden.

The area of a square is given as:

`\begin{gathered} A=L^2 \\ \text{where L = length of sides} \end{gathered}`

This means that:

`\begin{gathered} 225=L^2 \\ \text{ Find the square root of both sides:} \\ \Rightarrow\text{ L = 15 feet} \end{gathered}`

The perimeter of a square is given as:

P = 4L

So, the perimeter of the garden will be:

P = 4 * 15

P = 60 feet

The perimeter will be 60 feet.
