To find the length of the scale drawing, use the ratio of the width in real life to the width in the scale drawing:
24 feet / 36 feet = 8 inches / x
Solving for x, we get:
x = 36 * 8 / 24
x = 12 inches
Now that we have both the width and length in the scale drawing, we can find the perimeter of the mural in the scale drawing:
Perimeter = 2(width + length)
Perimeter = 2(8 + 12)
Perimeter = 2(20)
Perimeter = 40 inches
Therefore, the PERIMETER of the mural in the scale drawing is 40 inches.
