Answer:

The length of the second person ski's will be 189 cm.

Step-by-step explanation:

Michiko knows that a person's height is proportional to his or her correct ski length.

The person who is 70 inches tall, needs 210-centimeter skis.

The second client is 63 inches tall. Let his ski b 's' cm.

The relation forms:

[tex]\frac{70}{210} =\frac{63}{s}[/tex]

[tex]70s=210\times63[/tex]

=> [tex]70s=13230[/tex]

s = [tex]\frac{13230}{70}[/tex]

s = 189

Hence, the length of the second person ski's will be 189 cm.
