Question

The large rectangle's dimensions are three times the dimensions of the small rectangle. It is #60

Answer 1

A. Larger rectangle is 3 times bigger in perimeter.
B. Larger rectangle is 9 time bigger in area.
C. The answers are not the same because the scale factor is 3, then the perimeter of large rectangle would have a perimeter 3 times bigger than the small one. Also, the area would be found by taking the scale factor of 3 and squaring it 3^2=9 since it is a square unit.
D. What happens is that now we have a scale factor of 2 so the perimeter would be 2 times bigger for the larger rectangle and the area would be 2^2=4 times bigger than the small one.
