    First of all find the area of the smaller rectangle. Do you know the formula for it?

    lets say area of smaller rectangle is A1 and larger A2, now the ratio of areas is given as follows \[\frac{ A _{1}}{ A _{2} }=\frac{ 3*9 }{ 5*15 }=\frac{ 9 }{ 25 }\]

    Find the area of smaller rectangle first by putting length = 3 ft. and breadth = 9 ft. then find the area of larger rectangle. You can find the ratios of the areas by : \(\cfrac{\textbf{Area of smaller rectangle}}{\textbf{Area of Larger rectangle}} = \textbf{Required ratio}\)
