Answer:
<h2>The scale is 1 inch rep 4 feet or </h2><h2>1:4</h2>
Step-by-step explanation:
This problem is on ratios, the ratio of one quantity to another is a way to represent their relative size.
Moreso, the scale of a drawing tells us to what extent the drawing has been increased (maximized) or decresed (minimized)
now given that the actual dimention of the appartmentis 28ft wide
and on the drawing the apartment is 7 inches wide, we can see that the actual dimension has been reduced by a factor of 28/7= 4
hence the scale to represent this reduction is
1 inch to represent 4 feet
