Step-by-step explanation:
Answer:there is no g .no h
Step-by-step explanation:how can we tell u have a calculator right
P = a + b + c
a = shorter side
b = a + 12
c = a + 34
187 = a + (a + 12) + (a + 34)
187 = 3a + 46
187 - 46 = 3a
141 = 3a
141/3 = a
47 = a
b = a + 12 = 47 + 12 = 59
c = a + 34 = 47 + 34 = 81
lengths of 3 sides are : 47 in, 59 in, 81 in
