Answer:

The perimeter can not be 26 inches

Explanation:

Given

$Side\ 1 =19$

$Side\ 2 =16$

Required

Is a perimeter of 26 possible?

First, calculate the possible side 3

$Side\ 3 = Perimeter - Side\ 1 - Side\ 2$

$Side\ 3 = 26 - 16 - 19$

$Side\ 3 = -9$

The side length can not be negative.

So, the perimeter can not 26 inches
