Answer:
38 cm
Step-by-step explanation:
The perimeter of the figure is the sum of the lengths of all its sides.
We have two unknown length, so let's find their lengths first.
x= 10 -6= 4 cm
y= 9 -2= 7cm
Let's add all the lengths together to find the perimeter:
Perimeter
= 9 +10 +2 +6 +7 +4
= 38 cm
The difference is
302
-129
_____
173
to prove this

+129
_____
3+ 9 is 12 so the unity is 2 and you plus 1 to the tenth; 7 + 2 is 9 but if you plus the number that remained in the unity is 10 so the the tenth is 0 and you will plus 1 to the hungred, 1+1 is 2 but if you plus the 1 that remained in the tenth is 3, so if we put them all together it will be 302
