40 inches

Answer 1

To find the length in the scale drawing, we can set up a proportion:

24 feet (actual width) / 36 feet (actual length) = 8 inches (scale width) / x (scale length)

Solving for x, we get:
x = (8 inches * 36 feet) / 24 feet
x = 12 inches

So, the scale length of the mural is 12 inches.

To find the perimeter in the scale drawing, we add up the width and length of the scale drawing:

Perimeter = 2(8 inches) + 2(12 inches)
Perimeter = 16 inches + 24 inches
Perimeter = 40 inches

Therefore, the perimeter of the mural in the scale drawing is 40 inches.
