Answer 1

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

$60\%=60/100=0.60$

so

The length of the first copy of the picture is

$30(0.60)=18\ cm$

2) The copy is then scaled by 60% again

so

The length of the second copy of the picture is

$18(0.60)=10.8\ cm$
