4/6
As there are 4 numbers on the dice and there are 6 numbers all together on a dice.
Hope this helps
Perimeter is all sides added up.
Area is sometimes length times width with four sided figures like a rectangle or a square and for like triangles it is base times height.
The missing side would be 7 :)
The answer to x is 30 because if you do x+2x+3x=180 you can isolate for x
6x=180
x=180/6
x=30
