Asking Question: Myself

Question: poster measures 150cm by 180cm is enlarged in the ratio 8:5 find the length and breath of the enlarged poster.

Thank you very much
Hope to hear from you soon


Hi Sonu.

This could mean either of two things:

1) That the dimensions of the poster are each to be multiplied by 8/5 or
2) That the area of the poster is to be multiplied by 8/5 with the aspect ratio of 150:180 maintained.

The former interpretation is the more likely one; the latter is important when surface area is what really matters though. For example, a towel that 100cm by 50cm is four times "larger" than one that is 50cm by 25cm.

Hope this helps you.
