There is a field fenced in by a rectangular fence. Bob counts 20 fenceposts on one side and 18 on the other. If the fence posts are 2 feet apart, how big is the field, in square feet?

18 posts make for  17  spaces     17 x 2 = 34 ft

20 posts make 19 spaces             19 x 2 = 38

 

38 x 34 = 1292 sq ft
