Answer:
10.8 cm
Step-by-step explanation:
we know that
1) A square picture with side length 30 cm is scaled by 60% on a photocopier
Remember that
[tex]60\%=60/100=0.60[/tex]
so
The length of the first copy of the picture is
[tex]30(0.60)=18\ cm[/tex]
2) The copy is then scaled by 60% again
so
The length of the second copy of the picture is
[tex]18(0.60)=10.8\ cm[/tex]
Based on the information given, the side length of the second copy of the picture is 10.8cm.
Therefore, the side length will be:
= 30 × 60% × 60%
= 10.8cm
In conclusion, the correct option is 10.8cm.
