Each of the four shapes represents a positive whole number. The sum of the shapes in each row and column is displayed at the end of each row and column. Using this information, determine the numerical value of each shape.

     C₁   C₂   C₃   C₄     T

R₁   4     3    3      1      11  

R₂   1     2     1      2      6

R₃   2    3     4      2     11

R₄   1     1      3      1     6

T     8    9      11    6

Step-by-step explanation:

1.-For inspection  column 4 (C₄) is equal to row 2 ( R₂ ), and column 3 (C₃) is equal to row 1 (R₁)

2.- Let´s assume spiral is equal to 1 and the zebra rectangle is equal to 2
