If the Longfellow Playground is rectangular, what is its width?
(1) The ratio of its length to its width is 7 to 2.
(2) The perimeter of the playground is 396 meters.
It takes time and effort to explain, so if my comment helped you please press Thanks button :)



Just because something is hard doesn't mean you shouldn't try,it means you should just try harder.

1) is not sufficient
2) alone is not sufficient

Combining (7x+2x)*2 = 396
x = 11

length = 7x and breadth is 2x
