#1

Perimeter of a rectangle = 2*(Length + Width)

In other words, the sum of all sides.

So  5+5+12+12=34 which is D  2*(12+5)=2*17=34 D 

 

#2

Just count each mark from left to right, it is already labelled that 0 is the first mark, then the second is 1 and so on till you reach B which will be 8 (D)

 

#3

I think 2? C

 

#4

 

B) 3 and 2 Z shape.
