Selina has a 9 meter by 12 meter lawn that she wants to water. She has two Sprinklers, each of which can water grass within an 8.4-meter
radius in a 90° arc Selina wants to set up the two sprinklers so that they are on corners of the lawn. She would like for the sprinklers to
water as much of the lawn as possible, because she will have to manually water the part of the lawn that is not covered by the sprinklers.
Selina considers two different strategies for placing the sprinklers. One strategy is to put the sprinklers at opposite ends of a 12-meter side
of the lawn. The other is to put the sprinklers at opposite corners of the lawn. (See the figures below.) Which strategy appears to be best?
