A square garden has an area of 147 square feet.

options:

1. What is the closest approximate length of one of the sides?_______

2. What is the approximate perimeter of the garden to find out how much fencing you would need to go around it? _______

options for 1:
12 feet
11 feet
13 feet
10 feet

options for 2:
52 feet of fencing
24 feet of fencing
36 feet of fencing
49 feet of fencing

1 answer

To solve the questions, we'll first calculate the length of one side of the square garden based on its area, and then use that to find the perimeter.

  1. The area of a square is given by the formula: \[ \text{Area} = \text{side}^2 \] Given that the area is 147 square feet: \[ \text{side}^2 = 147 \] To find the side length, take the square root: \[ \text{side} = \sqrt{147} \approx 12.12 \text{ feet} \] The closest approximate length of one of the sides from the given options is 12 feet.

  2. The perimeter of a square is given by: \[ \text{Perimeter} = 4 \times \text{side} \] Using the previously calculated side length: \[ \text{Perimeter} = 4 \times 12.12 \approx 48.48 \text{ feet} \] The closest approximate value for the perimeter from the options given is 49 feet of fencing.

So, the answers are:

  1. 12 feet
  2. 49 feet of fencing
