Answer:
31.205
Step-by-step explanation:
The perimeter is the sum of the side lengths:
8.73 +12.4 +10.075 = 31.205
_____
If you're after an answer that has the appropriate precision (assuming these are measured values), that would be one that is rounded to 1 decimal place: 31.2.
It’d be 2=-2 ... but then subtract two from both side and the answer is a null set. Also known as “no solution”..
Best of luck in your studies :)
