in the scale drawing, each side is .38cm long. What is the perimeter of the actual object?
I have no ideas because I do not know the shape or the scale
To determine the perimeter of the actual object based on a scale drawing, you need to know the scale factor between the drawing and the actual object. If this information is not provided, it is not possible to accurately calculate the perimeter. The scale factor represents the ratio of the lengths in the drawing to the corresponding lengths in the actual object.
However, if you do have the scale factor, you can multiply the length of each side in the drawing by the scale factor to find the length of the corresponding side in the actual object. Then, you can sum up the lengths of all sides to find the perimeter of the actual object.
For example, if the scale factor is 1:10 (meaning each cm in the drawing represents 10 cm in the actual object), you would multiply .38 cm by 10 to get 3.8 cm. Since there are four sides, the perimeter of the actual object would be 4 * 3.8 cm = 15.2 cm.
So, to find the perimeter, you need to know the scale factor between the drawing and the actual object.
