Option A is the answer.
Explanation:
The length is given as = 12 feet
The width is given as = 4 feet
So, perimeter = [tex]2(l+w)[/tex]
= [tex]2(12+4)[/tex]
Perimeter = 32 feet
when the dimensions are multiplied by 6, so length becomes = [tex]12\times6=72[/tex] feet
width becomes= [tex]4\times6=24[/tex] feet
So, new perimeter becomes= [tex]2(72+24)[/tex]
= 192 feet
Dividing the new perimeter with old one = [tex]\frac{192}{32}=6[/tex]
Hence, The perimeter is increased by a factor of 6.
