If a rectangle that has the dimensions of 3 in by 8 in is enlarged using a scale factor of 2.5, what will be the new perimeter?

55 in

Step-by-step explanation:

Enlarged length = 2.5 × 8 in

                           = 20 in

Enlarged breadth = 2.5 × 3 in

                              = 7.5 in

Enlarged perimeter = 20 in + 20 in + 7.5 in + 7.5 in

                                 = 55 in

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.

according to egenuity the answer is
