Hilda's rectangle: w and L, L=w+5.

Jenny's square: w and w are the dimensions.

Ratio of areas of the rectangle to the square:
wL%2Fw%5E2
w%28w%2B5%29%2Fw%5E2
highlight%28%28w%2B5%29%2Fw%29-----ratio of the area of Hilda's banner to the area of Jenny's banner.

The final question means to evaluate the ratio expression for w=3.
