Amy is making scale drawings of different things in her neighborhood. One house she drew is 30 feet wide. Her scale drawing of the house is 5 inches wide. Which of the following uses the same scale Amy used to draw this house? Is this right my answer below?

29.5 foot wide play ground is represented by a 4.5 inch wide drawing.

30 feet = 360 inches

360/5 = 72 to 1

4.5 inches * 72 = 324 inches = 27 feet not 29.5

The choices are that one or

3 foot tall mail box is represented by an 18 inch tall drawing

or the 29.5 foot wide play ground answer

3/18 = 5/30

yes

Thank you, thank you. I thought I was forgotten :(

You are welcome.

To determine if your answer is correct, we need to check if the ratios of the widths in the original drawing and the new drawing are the same.

In Amy's scale drawing, 30 feet is represented by 5 inches.

Let's calculate the scale factor:
scale factor = width of original / width of drawing = 30 feet / 5 inches

Now let's apply this scale factor to the new scenario:

width of new drawing = scale factor * width of original
width of new drawing = (30 feet / 5 inches) * 4.5 inches
width of new drawing = 27 feet

So, if your answer was "27 foot wide play ground is represented by a 4.5 inch wide drawing," then it is correct because the scale factor is the same as Amy's scale drawing. However, if your answer was "29.5 foot wide play ground is represented by a 4.5 inch wide drawing," then it is not correct as the width of the new drawing should be 27 feet, not 29.5 feet.

No.
