Answer:
c
24
Step-by-step explanation:
A scale drawing is a reduced form in terms of dimensions of an original image / building / object
the scale drawing is usually reduced at a constant dimension
scale of the drawing = original dimensions / dimensions of the scale drawing
/LM/ is similar to /SR/
scale = 9 / 6 = 1.5 = 3/2
length of /ST/ = 12 / 1.5 = 8
Length of /TR/ = 15 / 1.5 = 10
Perimeter = sum of sides
8 + 10 + 6 = 24
