Hey there :)
y =
Since this line is parallel to the line to be found, both have the same slope:
Coordinates: ( - 9 , - 2 )
y - ( -2 ) = ( x - ( -9 ) )
y =
Since this line is parallel to the line to be found, both have the same slope:
Coordinates: ( - 9 , - 2 )
y - ( -2 ) =
The ratio of the length to the width is 
.
The ratio of the sides will be the same for the scale and actual figures.
I took the L/W of the scale figure
and set it equal to the L/W of the actual figure.
Now we can solve for the unknown width.
Cross-multiplication gives us this,
Divide by 2.4 and simplify,
Hope that helps! :)
