Question

Fabian used a ratio table to show the original dimensions of a rectangle and the dimensions when the rectangle is changed by a scale factor. He forgot to enter the length of the new rectangle.

Scale factor
1
2.5
Width
6
15
Length
9


Which length is missing from Fabian’s table?
3.6
11.5
21.6
22.5

Answer 1

The missing length from Fabian's table is 22.5.

The scale factor is 2.5, so to find the length of the new rectangle, we can multiply the original length (9) by the scale factor (2.5):

9 * 2.5 = 22.5

Therefore, the missing length in the table should be 22.5.
