The length of the original rectangle is = 8.4 cm
The width of the original rectangle is = 5.3 cm
Now we have been given that, the rectangle is enlarged by a scale factor of 4 which means both the dimensions are multiplied by 4 times.
So, new length of the rectangle is = [tex]8.4\times4=33.6[/tex] cm
New width of the rectangle is = [tex]5.3\times4=21.2[/tex] cm
Hence, the dimensions of the enlarged rectangle are 33.6 cm by 21.2 cm.
