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
![60\%=60/100=0.60](https://tex.z-dn.net/?f=60%5C%25%3D60%2F100%3D0.60)
so
The length of the first copy of the picture is
![30(0.60)=18\ cm](https://tex.z-dn.net/?f=30%280.60%29%3D18%5C%20cm)
2) The copy is then scaled by 60% again
so
The length of the second copy of the picture is
![18(0.60)=10.8\ cm](https://tex.z-dn.net/?f=18%280.60%29%3D10.8%5C%20cm)
