Question

If a triangle has sides that are 7.5cm, 15.5cm, and 22cm long, what is the perimeter of the triangle?

Answer 1

This one's pretty simple. Perimeter is the sum of all the sides, and you've been given the measurements for all three sides, which makes your life a lot easier. Add up the sides.
7.5 +15.5+22
This equals 45 cm. There's your perimeter. :)
