Question

Help me ans should be well explained ​

Answer 1

Finding diagonal sum

$\\ \sf\longmapsto 0.7+1.0+1.3$

$\\ \sf\longmapsto 0.7+2.3$

$\\ \sf\longmapsto 3.0$

#b

Observing the square

• x=0.9
• y=0.6

$\\ \sf\longmapsto xy=0.9(0.6)$

$\\ \sf\longmapsto xy=0.54$

Answer 2

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
