Question

the length and width of a rectangle are consecutive odd intergers. the area of the rectangle is 35 square units. what are the length and width of the rectangle?

Answer 1

The length and width must compel with the following standards:
(1) consecutive odds
(2) intergers

the possible pairs to satisfy condition (2) are 1x35 and 5x7
5 and 7 are consecutive odd numbers = satisfy condition (1)

=> the area's length and width is 5x7 or 7x5
=> it's 5 and 7 (or 7 and 5, doesn't really matter)
