Answer:

Step 1. Perimeter P means adding up all three sides of a triangle.

Step 2. Then P=s+s+s=3s where s is the length of the side of the equilateral triangle.

Step 3. ANSWER: Perimeter P=3s.

Answer:

p = 3k

45cm

Step-by-step explanation:

Since all sides of an equilateral triangle are equal, to find perimeter, you multiply the number of sides by the length of one side.

So the equation would be p = 3k (k represents the side length and 3 is the number of sides)

If a equilateral triangle has a side length of 15, you just multiply 15 by the number of sides.

3 (15cm) = 45cm

Answer:

C. √2 - 1

Step-by-step explanation:

If we draw a square from the center of the large circle to the center of one of the small circles, we can see that the sides of the square are equal to the radius of the small circle (see attached diagram)

Let r = the radius of the small circle

Using Pythagoras' Theorem a^2+b^2=c^2

(where a and b are the legs, and c is the hypotenuse, of a right triangle)

to find the diagonal of the square:

\implies r^2 + r^2 = c^2

\implies 2r^2 = c^2

\implies c=\sqrt{2r^2}

So the diagonal of the square = \sqrt{2r^2}

We are told that the radius of the large circle is 1:

⇒ Diagonal of square + r = 1

\implies \sqrt{2r^2}+r=1

\implies \sqrt{2r^2}=1-r

\implies 2r^2=(1-r)^2

\implies 2r^2=1-2r+r^2

\implies r^2+2r-1=0

Using the quadratic formula to calculate r:

\implies r=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}

\implies r=\dfrac{-2\pm\sqrt{2^2-4(1)(-1)}}{2(1)}

\implies r=\dfrac{-2\pm\sqrt{8}}{2}

\implies r=-1\pm\sqrt{2}

As distance is positive, r=-1+\sqrt{2}=\sqrt{2}-1  only
