Answer
The scale Mabel used for the drawing is
1 inch = 4 feet.
Step-by-step explanation
On Mabel's drawing, the tent is 2 inches wide. But in real life, the actual tent is 8 feet wide.
So,
2 inches on Mabel's drawing = 8 feet in real life
2 inches = 8 feet
Divide both sides by 2 in order to obtain the scale used
(2 inches)/2 = (8 feet)/2
1 inch = 4 feet.
Hope this Helps!!!
