What is the perimeter of a triangle with sides measuring 3, 4, and 5 units?

10 units

12 units

To find the perimeter of a triangle, you simply add the lengths of all its sides together. In this case, the triangle has sides measuring 3, 4, and 5 units.

Calculating the perimeter involves the following steps:

1. Add the first side (3 units) to the second side (4 units), which gives you 7 units.

2. Then, add the third side (5 units) to this sum: 7 units + 5 units equals 12 units.

Thus, the perimeter of the triangle is 12 units. This value reflects the total distance around the triangle, which is precisely what the perimeter is designed to measure.
