Question

The actual length (L) of a rectangle is 27 centimeters. Use the scale drawing of the rectangle to find the actual width.

Width = 2.4 cm

Answer 1

To find the actual width of the rectangle, we will first find the scale factor between the length in the scale drawing and the actual length.

Scale factor = Actual length / Length in scale drawing
Scale factor = 27 cm / L in scale drawing

Given that the length in the scale drawing is 3 cm, we can calculate the scale factor:
Scale factor = 27 cm / 3 cm
Scale factor = 9

Now, we can find the actual width using the scale factor and the width in the scale drawing:
Actual width = Width in scale drawing x Scale factor
Actual width = 2.4 cm x 9
Actual width = 21.6 cm

Therefore, the actual width of the rectangle is 21.6 centimeters.

Answer 2

18 is the correct answer I just did the math with the given formula..

27 divided by 3.6 = 7.5

then

multiply 2.4 by 7.5

=18

Answer 3

I apologize for the error in my previous response. Thank you for providing the correct calculation.

Using the formula as you did:

Scale factor = Actual length / Length in scale drawing
Scale factor = 27 cm / 3.6 cm
Scale factor = 7.5

Actual width = Width in scale drawing x Scale factor
Actual width = 2.4 cm x 7.5
Actual width = 18 cm

Therefore, the correct actual width of the rectangle is indeed 18 centimeters. Thank you for pointing that out.
