rectangular cake pans x and y are similar. the ratio of the width of pan x to the width of pan y is 3:5. the length of pan x is 12 inches and its width is 6 inches. what is the perimeter if pan y?

3/5 = 12/L.
3L = 60.
L = 60/3 = 20 In = Length of y.
3/5 = 6/W.
3w = 30.
W = 10 In. = Width of y.
P = 2W + 2L = 2*10 + 2*20 = 60 In. = Perimeter of y.
