Rusty is building a doghouse for his dog, Wheezer. He is making the dimensions of the doghouse proportional to his own house, which has a length of 54 feet and a width of 36 feet. If wheezer's new home is going to have a length of 6 feet, what will be the width?
54/36 = 6/x
Cross multiply and solve for x.
54x = 216
x = 4
