Question

A triangle has side lengths of (10f + 6) centimeters, (2f-4) centimeters, and

(9g + 1) centimeters. Which expression represents the perimeter, in centimeters, of
the triangle?

Answer 1

The perimeter of the triangle is the sum of the lengths of all three sides. Therefore, the expression for the perimeter is:

(10f + 6) + (2f-4) + (9g + 1)

Simplifying the expression:

= 12f + 9g + 3

Therefore, the expression for the perimeter of the triangle is 12f + 9g + 3 centimeters.
