Question: In triangle STU, if ST = 12 cm, TU = 16 cm, and SU = 20 cm, what is the perimeter of triangle STU?

Options:

Correct Answer: 36 cm

Solution:

The perimeter of triangle STU is ST + TU + SU = 12 + 16 + 20 = 48 cm.

In triangle STU, if ST = 12 cm, TU = 16 cm, and SU = 20 cm, what is the perimeter of triangle STU?

In triangle STU, if ST = 12 cm, TU = 16 cm, and SU = 20 cm, what is the perimeter of triangle STU?

Step 1: Identify the lengths of the sides of triangle STU. They are ST = 12 cm, TU = 16 cm, and SU = 20 cm.
Step 2: Write down the formula for the perimeter of a triangle, which is the sum of the lengths of all its sides.
Step 3: Substitute the lengths of the sides into the formula: Perimeter = ST + TU + SU.
Step 4: Calculate the sum: 12 cm + 16 cm + 20 cm.
Step 5: Add the numbers together: 12 + 16 = 28, then 28 + 20 = 48.
Step 6: State the final answer: The perimeter of triangle STU is 48 cm.

Perimeter of a Triangle – The perimeter of a triangle is calculated by adding the lengths of all its sides.
