Question

The sides of a triangle measure 2.24 inches, 3.56 inches, and 4.50 inches. What is the perimeter of this triangle? Report the answer with the appropriate number of significant digits. 10.0 inches 10.3 inches 10.30 inches 10 inches

Answer 1

The perimeter would be 10.3 because when you add all the numbers you get 10.30 but since the lowest number of sig figs from all the numbers is 3, the answer would be 10.3 (3 sig figs)

Answer 2

To find the perimeter of a triangle, you can use the formula P = a + b + c. 2.24 would be a, 3.56 would be b, and 4.50 would be c. Then, you add up the terms and get your perimeter: 10.3
