Item 16 a rectangular garden is 6 feet long and 4 feet wide. a second rectangular garden has dimensions that are double the dimensions of the first garden. what is the percent of change in perimeter from the first garden to the second garden?

We know that

first garden dimensions > 6 feet long x 4 feet wide
second garden dimensions> (6*2) feet long x (4*2) feet wide
then
second garden dimensions> (12) feet long x (8) feet wide

[perimeter first garden]=2*6+2*4> 20 ft
[perimeter second garden]=12*2+8*2> 40 ft

[the percent of change in perimeter]=[[perimeter second garden]-[perimeter first garden]}/[perimeter first garden]
[the percent of change in perimeter]=(40-20)/20> 1> 1*100> 100 %

the answer is 100%
