A drawing has a scale of 1cm=2ft.If the object drawn has a length that measures 8.5cm, what is the objects actual length.
The answer I have is 17ft. Is this correct?
Yes, it's correct.
yes
Yes, your answer of 17ft is correct.
To understand how to arrive at this answer, let's break down the given information.
The scale of 1cm = 2ft means that for every centimeter on the drawing, it represents 2 feet in actual size.
Now we know that the length on the drawing is 8.5cm. To find the object's actual length, we need to convert this length from centimeters to feet.
To do that, we multiply the length on the drawing (8.5cm) by the conversion factor, which is 2ft/1cm. This will cancel out centimeters and leave us with the length in feet.
So, multiplying 8.5cm by 2ft/1cm:
8.5cm * (2ft/1cm) = 17ft
Therefore, the object's actual length is 17ft.
