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 

Answer 2

In this question, it is given that the scale factor is
`1:2.5`

And the widths are 6 and 15.

And the length is 9.

We have to find the measurement of the length after the scale factor .

And for that we multiply 9 with the scale factor, and on doing so, we will get

`9*2.5 = 22.5`

So the missing length is 22.5
