We can use the equation
to find the length of the side of a square.
<u>Solution:</u>
Given that, the perimeter of a square is equal to the perimeter of an equilateral triangle.
The length of a side of the square is given by "x"
And the length of a side of the equilateral triangle is given by "y"
Finding the equation to determine value of "x"
<em><u>The perimeter of a square with side "x" is given as:</u></em>

<em><u>Perimeter of a equilateral triangle with side "y" is given as:</u></em>

Given that perimeter of a square = perimeter of an equilateral triangle

Hence, we can use the equation
to find the length of the side of a square.
Answer:
8
Step-by-step explanation:
Answer:
8.94 m
Step-by-step explanation:
Use the Pythagorean Theorum -
. Use leg 1 as <em>a</em>, leg 2 as <em>b</em>, and the third side as <em>c</em>.
We know leg 1 is 4, and that leg 2 is twice as long as leg 1...

Now, we use the Order of Operations to find
...

Now, we find the square root of
to find c...

So, the length of the third side is 8.94 m.
