Jill’s room is 12.5 feet long and 11.5 feet wide. She made a scale drawing of the room with a scale of 0.5 inch = 2 feet. What is the perimeter of Jill’s room in the drawing?
A. 12 inches
B. 24 inches
C. 48 inches
D. 96 inches
first of all look at what I did a minute ago for someone else:

12.5 ft (.5 in/2 ft) = 3.125 in
11.5 ft (.5 in/ 2 ft) = 2.875 in
so
2*3.125 + 2*2.875 = 12 in
Do you have video of the break down of how you got 3.125 and 2.875
Well, well, well. Jill's room seems to be quite the puzzle! Let's do some calculations, shall we?
The length of Jill's room is 12.5 feet. According to the scale of 0.5 inch = 2 feet, we can use proportions to determine the length in the drawing.
12.5 feet * (0.5 inch / 2 feet) = 3.125 inches
Now let's do the same thing for the width of the room. The width of Jill's room is 11.5 feet.
11.5 feet * (0.5 inch / 2 feet) = 2.875 inches
To find the perimeter of the room in the drawing, we can simply add up all the sides.
Perimeter = 3.125 inches + 3.125 inches + 2.875 inches + 2.875 inches
Perimeter = 12 inches
So, the perimeter of Jill's room in the drawing is 12 inches. Looks like option A is the correct answer!
To find the perimeter of Jill's room in the drawing, we need to consider the scale of the drawing. The scale mentioned is 0.5 inch = 2 feet.
First, let's calculate the length and width of the room in inches, which will represent the dimensions in the drawing.
Length in inches = Length in feet * Scale
Width in inches = Width in feet * Scale
Length in inches = 12.5 feet * (0.5 inch / 2 feet) = 12.5 feet * 0.25 inch/foot = 3.125 inches
Width in inches = 11.5 feet * (0.5 inch / 2 feet) = 11.5 feet * 0.25 inch/foot = 2.875 inches
Now, we can calculate the perimeter of the room in the drawing by adding up all four sides of the room.
Perimeter = 2 * (Length in inches + Width in inches)
Perimeter = 2 * (3.125 inches + 2.875 inches)
Perimeter = 2 * 6 inches
Perimeter = 12 inches
Therefore, the perimeter of Jill's room in the drawing is 12 inches. So, the correct answer is A. 12 inches.
