Question: In triangle PQR, if PQ = 8 cm, QR = 6 cm, and PR = 10 cm, what is the perimeter of the triangle? (2022)

Options:

Correct Answer: 24 cm

Exam Year: 2022

Solution:

Perimeter = PQ + QR + PR = 8 + 6 + 10 = 24 cm.

In triangle PQR, if PQ = 8 cm, QR = 6 cm, and PR = 10 cm, what is the perimeter of the triangle? (2022)

In triangle PQR, if PQ = 8 cm, QR = 6 cm, and PR = 10 cm, what is the perimeter of the triangle? (2022)

Step 1: Identify the lengths of the sides of triangle PQR. They are PQ = 8 cm, QR = 6 cm, and PR = 10 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 values of the sides into the formula: Perimeter = PQ + QR + PR.
Step 4: Calculate the sum: 8 cm + 6 cm + 10 cm.
Step 5: Add the numbers together: 8 + 6 = 14, then 14 + 10 = 24.
Step 6: State the final result: The perimeter of triangle PQR is 24 cm.

Perimeter of a Triangle – The perimeter of a triangle is the sum of the lengths of all its sides.
