A rectangular garden has width 2 m and length 3 m. The width of the garden is initially increased by 1.5 m. In order for the transformation to be proportional, by how much should the length increase?

Width goes from   2    to    3.5    scale factor   1.75

 

3 x 1.75 = 5.25      length must increase from  3   to  5.25      2.25 m increase
