An equilateral triangle has three equal sides. Write a relation for the perimeter of an equilateral triangle with side length k.
What is the perimeter of an equilateral triangle with side length 15 cm?

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.

I hope the above steps and explanation were helpful.

Step-by-step explanation:

HOPE THIS HELPS

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

once you graph it hit 2nd (the blue button) and graph

that takes you to a table of coordinates

on the left is x coordinates and on the right is y coordinates and an empty box

in the opening of the question the word 'service' is associated only with the pretax value.

the closing part of the question asks: how much did she pay for the
