Answer 2

Answer:

74 cm would a ribbon need to be to go all the way around the edge of the top of the box .

Step-by-step explanation:

Formula

Perimeter of a rectangle = 2 (Length + Breadth)

As given

The rectangular top of a small box has dimensions of 140 mm by 230 mm.

Perimeter of the rectangle box top = 2 × (140 + 230)

                                                          = 2 × 370

                                                          = 740 mm

As

1 mm = 0.1 cm

Now change into 740 mm into cm.

740 mm = 0.1 × 740  

              = 74 cm

Perimeter of the rectangle box top = 74 cm

Therefore 74 cm would a ribbon need to be to go all the way around the edge of the top of the box .
