What is the value of P for the following triangular prism?
36 cm
36 mm
10.8 cm
14.55 cm

Answer:
10.8 cm
Step-by-step explanation:
we know that
The perimeter of the triangular face is equal to the sum of its sides
P=a+b+c
we have
a=28 mm=28/10=2.8 cm
b=4 cm
c=4 cm
substitute the values
P=2.8+4+4=10.8 cm
