The sides of a triangle measure 2.22 inches, 3.54 inches, and 4.5 inches. what is the perimeter of this triangle? report the answer with the appropriate number of significant digits.

Finding the Perimeter When Three Side Lengths are Known. Remember the formula for finding the perimeter of a triangle. For a triangle with sides a, b and c, the perimeter P is defined as: P = a + b + c.

So the equation would be 2.22+3.54+4.5=p

2.22+3.54+4.5=10.26
