Question

A rectangular school banner has a length of 60 inches and a width of 48 inches. A sign is made that is similar to the school banner and has a length of 14 inches. What is the ratio of the area of the school banner to the area of the sign?

Answer 1

The ratio of the length of the banner to the length of the sign = 54/17

So....since they are similiar figures, the widths will have the same ratio

And the ratio of the area of the banner to the area of the sign will be the square of this ratio

Explanation:

[54/17]^2 = 2916/289
