22x2.5=55

or 8x2.5
3x2.5

Answer:

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
