Question

a triangle has side lengths of 1.3 k + 3.5 in centimeters 4.1 k -1.6 in centimeters and 9.7 in + 4.4 m centimeters which expression represents the perimeter and centimeters of the triangle

Answer 1

We have the following:

the perimeter is the sum of all the sides of the triangle, therefore:

$\begin{gathered} p=1.3k+3.5m+4.1k-1.6n+9.7n+4.4m \\ p=(1.3k+4.1k)+(9.7n-1.6n)+(3.5m+4.4m) \\ p=5.4k+8.1n+7.9m \end{gathered}$

Therefore, the answer is the first option
