Question

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.

Answer 1

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
