How can you find the side length of the triangle when the perimeter is 22cm?

Answer 1

You can't. The perimeter doesn't reveal the side lengths. It tells you what

you get when you add up the three lengths, but there are an infinite number

of possible sets of three sides that add up to the same total.

For example, a triangle with a perimeter of 22 could have sides of

2, 10, 10

4, 9, 9

5, 7, 10

6, 7, 9

7, 7, 8

etc.
