Rectangular cake pans X and Y are

similar. The ratio of the width of
pan X to the width of pan Y is 3 : 4.
The length of pan X is 10 inches, and
its width is 5 inches. What is the
perimeter of pan Y ?

2 answers

X is 5 by 10
Y:x = 4/3, so
Y is 20/3 by 40/3
and its perimeter is thus 40

or

X is 5 by 10,
so its perimeter is 30
Y:X = 4:3, so its perimeter is 40
