I will go in order from left to right on the top row, then go down to the bottom row and go from left to right. (btw most of these are just cutting shapes into smaller pieces)

80+10=90cm
2nd shape:36+60=96cm
3rd shape: 56+(4*8/2) 56+16=72cm
4th shape: 12+55+5= 12+60=72 cm
5th shape:4+88=92 cm
6th shape:68 as it is the last option
