Answer:
The actual width of the bakery is 420 feet.
Step-by-step explanation:
If the scale of Martha's drawing is 1 inch : 5 feet, it means that every 1 inch in the drawing represents 5 feet in reality.
Given that the width of the bakery in the drawing is 7 inches, we can calculate the actual width of the bakery by multiplying the drawing width by the scale factor.
Actual width of the bakery = Drawing width * Scale factor
Drawing width = 7 inches
Scale factor = 5 feet / 1 inch
Now, Performing the calculation:
Actual width of the bakery = 7 inches * 5 feet / 1 inch
To cancel out inches in the numerator and denominator, we multiply by 12 inches / 1 foot:
Actual width of the bakery = (7 inches * 5 feet / 1 inch) * (12 inches / 1 foot)
Simplifying the units:
Actual width of the bakery = (7 * 5 * 12) feet
Calculating:
Actual width of the bakery = 420 feet
Therefore, the actual width of the bakery is 420 feet.
