Answer:

Step-by-step explanation:

Assuming that it follows some sort of law, a proportion should answer the question. The problem: is the ratio an area or is it linear. I'll assume it is linear. If it is marked wrong, leave a note.

2.5/168::4/x                         Cross multiply

2.5x = 168 * 4

2.5x = 672                           Divide by 2.5

x = 672/2.5

x = 268.8
