For this case we can do the following:


And then if we multiply we got:
Answer:
Perimeter = 78.7 inches
Step-by-step explanation:
From the given question, applying the Pythagoras theorem to one of the congruent triangles formed, we have;
=
+ 
=
+ 
=841 + 81
= 922
hyp = 
= 30.3645
The perimeter of the triangle can be determined as;
perimeter =
+
+ 
= 30.3645 + 18 + 30.3645
= 78.729
The perimeter of the triangle = 78.7 inches
"a" is an absolute value, so that means that after whatever is in the brackets is solved as far as it can be, it becomes a positive value, no matter what it is. So, |-1.4| is equal to 1.4. The equation is 1.4+ (-2.7) or 1.4 - 2.7 which equals -1.3
