Question: If the perimeter of an equilateral triangle is 36 cm, what is the length of one side?

Options:

Correct Answer: 12 cm

Solution:

Perimeter = 3 * side. Therefore, side = Perimeter / 3 = 36 / 3 = 12 cm.

If the perimeter of an equilateral triangle is 36 cm, what is the length of one side?

If the perimeter of an equilateral triangle is 36 cm, what is the length of one side?

Step 1: Understand that an equilateral triangle has all three sides equal.
Step 2: Know that the perimeter of a triangle is the total length around it, which is the sum of all its sides.
Step 3: For an equilateral triangle, the perimeter can be calculated as 3 times the length of one side (Perimeter = 3 * side).
Step 4: We are given that the perimeter is 36 cm.
Step 5: To find the length of one side, we can rearrange the formula: side = Perimeter / 3.
Step 6: Substitute the given perimeter into the formula: side = 36 cm / 3.
Step 7: Calculate the result: side = 12 cm.

Perimeter of an Equilateral Triangle – The perimeter of an equilateral triangle is calculated by multiplying the length of one side by 3.
Division – Understanding how to divide the total perimeter by the number of sides to find the length of one side.
