Answer 1

3.

Mona Lisa portrait:

Length = 30 in

width = 21 in

Magnet:

3.5 cm wide:

First, express cm into in:

1 in = 2.54 cm

3.5 cm = 1.37795 in ( divide by 2.54)

Ratio of widths: Portrait to magnet:

21 in / 1.37795 in = 15.24

Lenght:

30 / x = 15.24

x = 30/15.24

x= 1.9685 inches. or = 5 cm

Answer:

Length of the magnet = 5 cm
