A rectangular school banner has a length of 36 inches and a width of 52 inches. A sign is made that is similar to the school banner and has a length of 22 inches. What is the ratio of the area of the school banner to the area of the sign?

Question

What is the ratio of the areas?

I tried doing 52/36 and multiplying that by 22. Then I tried getting the area by multiplying 22 and that number but I don't think its right.

Answer 1

Sign: W = 22/36 * 52 = 32.
Ab/As = (36*52)/(22*32) = 2.68.

Or Ab/As = (36/22)^2 = 2.68.
