To find the actual width of the bakery, we need to convert the measurement given in the drawing to the actual measurement using the scale.
If the scale is 20 inches : 7 feet, we can set up a proportion to find the actual measurement:
20 inches / 7 feet = 140 inches / x
To find x, we can cross-multiply and solve for x:
20 * x = 7 * 140
20x = 980
Dividing both sides of the equation by 20:
x = 980 / 20
x = 49
Therefore, the actual width of the bakery is 49 feet.
