AB= 32.5
BC= 65
perimeter : 214

10x-5=13x-26
-10x +26

21=3x
7=x

AB: 10(7)-5
70-5
65

BC: 13(7)-26
65


65(.5)= 32.5

perimeter: 65+65+84= 214

Answer: the perimeter is 214. AB's half is 32.5 and BC's whole is 65

Step-by-step explanation: 10x-5 and 12x-26 are equal, as shown by the marks on their lines, so we can set them equal to each other to solve for x. when solved x=7. then plug 7 into each equation to get 65. lastly add up 84+65+65 to get 214.
