Question 1151755
.
Two faulty tennis ball machines start to shoot balls from opposite sides of a 25
meter by 10 meter tennis court. The green ball machine shoots green balls that
stop on the court 5 meters to 20 meters from the green machine's side. The
yellow ball machine shoots yellow balls that stop on the court 2 meters to 16
meters from the yellow machine's side. Find the area of the tennis court that has
balls of either color on it.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



The balls cover the area from  min(5, 2) = 2 meters to  max(20,16) = 20 meters.


The length of this area is 20-2 = 18 meters.


Regarding the width of the area, the problem keeps silence about it,
but we can accept/admit that the width is equal to the width of the tennis court of 10 meters.


Thus the covered area is &nbsp;(or can be estimated as) &nbsp;18 * 10 = 180 square meters.    &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<U>ANSWER</U>
