Answer:
3.12
Explanation:
A rectangular room is 32 feet by 45 feet.
The Perimeter of the scale drawing of the room is 15 inches
So, the perimeter of the room
2(l+w)
2(32+45)=2(77) =154
calculate the scale factor
154/15 = 10.3 when you round it
Shorter side on-scale drawing
(Length of the shorter side of the actual room) / Scale factor
32 feet / (154 feet / 15 inches) = 3.12 when you round it
