A rectangular mural is 24 feet in width and 36 feet in length. A scale drawing of the mural has a width of 8 inches. Find the length. What is the PERIMETER, in inches, of the mural in the scale drawing?(1 point) Responses 68 inches 68 inches 20 inches 20 inches 12 inches 12 inches 40 inches 40 inches
To find the length of the scale drawing, we need to set up a proportion using the dimensions of the actual mural and the scale dimensions:
24 feet / 36 feet = 8 inches / x inches
Cross multiplying, we get:
24 * x = 36 * 8
24x = 288
x = 12
Therefore, the length of the scale drawing is 12 inches.
Now, to find the perimeter of the mural in the scale drawing, we need to find the dimensions of the scale drawing and add them up:
Width = 8 inches
Length = 12 inches
Perimeter = 2(width) + 2(length)
Perimeter = 2(8) + 2(12)
Perimeter = 16 + 24
Perimeter = 40 inches
Therefore, the PERIMETER, in inches, of the mural in the scale drawing is 40 inches.
