we know that
scale factor =5.5
the dimensions of the original rectangle are
length is  8 cm, and the width is  6 cm.
original perimeter=2*[8+6]
<hr class="bbcode_rule" />
> 28 cm
original area=8*6----> 48 cm²

kacchan · Answer

perimeter of the larger rectangle=[scale factor]*original perimeter
perimeter of the larger rectangle=5.5*28
<hr class="bbcode_rule" />
> 154 cm
