Answer:
A = 8, B = 6, C = 4 , D = 7
Top = 29
Side = 20
Step-by-step explanation:
Last row : A + A + A + A = 32 ==> A = 8
First row : D + A + D + D = 3D + 8 = 29
3D = 21 ==> D = 7
Second row : B + D + A + B = 27 ==> 2B + 7 + 8 = 27
2B = 12 ==> B = 6
Third column : D + A + C + A = 27
7 + 8 + C + 8 = 27 ==> C = 4
