Finding diagonal sum
[tex]\\ \sf\longmapsto 0.7+1.0+1.3[/tex]
[tex]\\ \sf\longmapsto 0.7+2.3[/tex]
[tex]\\ \sf\longmapsto 3.0[/tex]
#b
Observing the square
[tex]\\ \sf\longmapsto xy=0.9(0.6)[/tex]
[tex]\\ \sf\longmapsto xy=0.54[/tex]
Answer:
=====> A
⟼0.7+1.0+1.3
⟼0.7+2.3
⟼3.0
======> B
x=0.9
y=0.6
⟼xy=0.9(0.6)
⟼xy=0.54
