If you express "7.5 cm is 35% of the original dimension" mathematically you have
7.5 cm = 0.35 * OriginalDimension
so you can readily rearrange the expression as
7.5 cm/0.35 = OriginalDimension
Do the same for the 12.5 cm dimension

Multiply the % by the Original Dimensions
2.8125 and 4.6875
I think
