Finding the Area of a Garden
Hey there! Today, we are going to figure out how to find the area of a square garden using some math tricks. First, we have four points that will help us make a square.
Here are the points we have:
- A (−7, 6)
- B (−2, −6)
- C (10, −1)
- D (5, 11)
Step 1: Plotting the Points
Let’s start by plotting these points on a grid! You can draw a coordinate plane with x (horizontal) and y (vertical) lines:
- Point A is at (−7, 6). Go to the left 7 and up 6.
- Point B is at (−2, −6). Go to the left 2 and down 6.
- Point C is at (10, −1). Go to the right 10 and down 1.
- Point D is at (5, 11). Go to the right 5 and up 11.
After plotting these points, connect them in order to make Square ABCD.
Step 2: Finding the Side Length, s
Now, to find the side length of the square (let's call it "s"), we can use the Pythagorean Theorem, which is a fancy way of saying that in a right triangle, the square of the longest side (hypotenuse) is equal to the sum of the squares of the other two sides.
To do this, we need to find the distance between two points. Let’s choose points A and B. We can use the distance formula:
\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} \]
For points A and B:
- \( (x_1, y_1) = (-7, 6) \)
- \( (x_2, y_2) = (-2, -6) \)
Plugging the numbers into the formula:
\[ d = \sqrt{((-2) - (-7))^2 + ((-6) - 6)^2} \]
\[ d = \sqrt{(5)^2 + (-12)^2} \]
\[ d = \sqrt{25 + 144} \]
\[ d = \sqrt{169} \]
\[ d = 13 \]
So, the side length \( s \) of Square ABCD is 13.
Step 3: Finding the Area
Finally, we can find the area of the square using the formula:
\[ A = s^2 \]
Plugging in our side length:
\[ A = 13^2 \]
\[ A = 169 \]
Conclusion
So, the area of Square ABCD is 169 square units. Awesome job using the Pythagorean Theorem! Now your garden has a nice area you can plan for! 🌼🌻
