Perimeter of a triangle

From the question, we are to determine the expression that represents the perimeter of the triangle

From the given information,

The triangle has side lengths of (3.8k - 8.4m) centimeters, (4.4k - 4.7n)

centimeters, and (1.7n + 1.2m) centimeters

The perimeter of a triangle is the sum of all its side lengths

Thus,

The perimeter of the triangle is

P = (3.8k - 8.4m) + (4.4k - 4.7n) + (1.7n + 1.2m)

P = 3.8k - 8.4m + 4.4k - 4.7n + 1.7n + 1.2m

P = 3.8k + 4.4k - 8.4m + 1.2m - 4.7n + 1.7n

P = 8.2k -7.2m -3n

OR

P = -7.2m + 8.2k - 3n

Hence, the expression that represents the perimeter, in centimeters, of the triangle is -7.2m + 8.2k - 3n
