James cut out four parallelograms, the dimensions of which are shown below.

Parallelogram 1

length: 12 in.
width: 15 in.
diagonal: 20 in.
Parallelogram 2

length: 16 in.
width: 30 in.
diagonal: 34 in.
Parallelogram 3

length: 20 in.
width: 21 in.
diagonal: 29 in.
Parallelogram 4

length: 18 in.
width: 20 in.
diagonal: 26 in.

James put the parallelograms together so one vertex from each paper exists on a point, as shown in the circle.
