Understanding the Problem
To find the perimeter of a triangle, you need to sum the lengths of all its sides. In this case, the triangle has sides measuring 4 cm, 6 cm, and 10 cm.
Calculating the Perimeter
The formula for the perimeter (P) of a triangle is:
P = side1 + side2 + side3
Inserting the values:
- Side 1 = 4 cm
- Side 2 = 6 cm
- Side 3 = 10 cm
Now, we calculate the perimeter:
- P = 4 cm + 6 cm + 10 cm
Performing the Addition
- First, add the first two sides:
- 4 cm + 6 cm = 10 cm
- Next, add this result to the third side:
- 10 cm + 10 cm = 20 cm
So, the perimeter of the triangle is 20 cm.
Conclusion
The correct answer is option 'A', which states that the perimeter is 20 cm.
Summary of Key Points
- The sides of the triangle are 4 cm, 6 cm, and 10 cm.
- The perimeter is calculated by summing the lengths of all sides.
- The final perimeter is 20 cm, confirming option 'A' is correct.
