Joel is a pizza delivery driver. He must deliver a pizza to a house on the diagonally opposite corner of the block, which measures 1.2km
wide by
2.1km
long. However, Joel realises he can save time if he takes a short cut, and he drives through the park in the middle of the block.

How long is Joel's new route through the middle of the park?

I’m quite confused, could someone help?
