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?
A 54-foot-tall water tower represented by a 9-inch drawing\
A 29.5 foot wide house represented by a 4.5 inch wide drawing***
a 24-foot wide house represented by a 5 inch drawing
a 3 foot tall mailbox measured by an 18 inch tall drawing
No.
Yes, A.
To find out which of the options uses the same scale as Amy's drawing of the 30-foot wide house, we need to compare the ratios of the widths in the options to the width of Amy's drawing.
First, let's find the ratio of the width of Amy's drawing to the actual width of the house:
Ratio = Width of drawing / Actual width of the house
Ratio = 5 inches / 30 feet
Now, let's compare this ratio with each option to see which one matches:
Option A:
Ratio = 9 inches / 54 feet
This ratio is different from Amy's drawing ratio, so it is not the correct answer.
Option B:
Ratio = 4.5 inches / 29.5 feet
This ratio matches with Amy's drawing ratio, so this is the correct answer.
Option C:
Ratio = 5 inches / 24 feet
This ratio is different from Amy's drawing ratio, so it is not the correct answer.
Option D:
Ratio = 18 inches / 3 feet
This ratio is different from Amy's drawing ratio, so it is not the correct answer.
Therefore, the correct answer is option B: a 29.5-foot wide house represented by a 4.5-inch wide drawing.
