in the scale drawing below each side is 1.29 cm long use the scale factor shown. what is the perimeter of the actual object
A( 12.325m
B( 52.125m
C( 41.925m
D( 61.675m
Umm what about people who need help with this answer? XD
True dat @Dat Boi
ugg i neded hlp grrrr ms sue na jk but still
Lol @Senpai
To find the perimeter of the actual object, we need to know the scale factor. However, you mentioned that the scale factor is not provided in the question. So, we'll first need to calculate the scale factor using the given information.
From the scale drawing, we know that each side on the drawing is 1.29 cm long. Let's assume that the corresponding sides on the actual object are "x" cm long.
To find the scale factor, we can set up a proportion using the lengths of the sides:
1.29 cm (length on the drawing) / x cm (length on the actual object) = 1 (scale factor)
Simplifying the equation, we have:
1.29 / x = 1
Next, we can cross-multiply and solve for x:
1.29 = x
Therefore, the scale factor is 1.29.
Now that we have the scale factor, we can calculate the perimeter of the actual object. The perimeter of a shape is the sum of all its sides.
Since all sides in the drawing are 1.29 cm long, we can multiply that by the scale factor to find the lengths of the corresponding sides on the actual object. Thus, each side of the actual object is 1.29 cm * 1.29 = 1.6641 cm long.
Since the actual object is most likely a polygon with four sides, we can calculate the perimeter by adding up the lengths of all four sides:
Perimeter = 1.6641 cm + 1.6641 cm + 1.6641 cm + 1.6641 cm = 6.6564 cm
However, the answer choices are given in meters, so we need to convert centimeters to meters. There are 100 centimeters in 1 meter, so dividing the perimeter by 100 will give us the answer in meters:
Perimeter (in meters) = 6.6564 cm / 100 = 0.066564 m
Rounded to three decimal places, the perimeter of the actual object is approximately 0.067 m.
Therefore, none of the answer choices provided match the calculated perimeter. It is possible that there was an error in the problem or the answer choices.
JJ -- isn't this about enough? Look at all of the questions you've posted in the last few days.

This isn't all of them either because you've also posted under different names.
Please do not post any more questions unless you also show the work you've done to solve this problem.
Guys lets just agree on Ms. Sue, please!
Y'all are jerks
