Given the area of the square ABCD is
Find the perimeter.
To find the perimeter of the square ABCD, we first need to determine the side length of the square using the given area. The area of a square is calculated using the formula: , where is the side length of the square.
According to the problem, the area of the square is given by the expression .
Let's simplify this expression:
First, calculate , which is .
Next, calculate , which is .
Now, multiply these results: .
Thus, the area of the square is .
Since the area is , we can solve for :
Find the square root of both sides: .
This gives .
Now that we have the side length , we can find the perimeter. The perimeter of a square is given by:
.
Substituting the side length, we get:
.
The solution to the question is:
\( 5+\sqrt{36}-1= \)
You must simplify to get a clear numerical value for the area. Without simplifying, you can't easily find the square root to get the side length!
Since we're finding a side length, we always take the positive square root. Side lengths can't be negative in geometry!
For this problem, is a perfect square. If you get non-perfect squares, use a calculator or leave it in radical form like .
Yes! If the perimeter is 24, then each side is . Check: Area = , which matches ✓
Let's check: , , and . All give perimeter 16, meaning side length 4 and area .
