#### DS Geometry problem - It is out of a UCLA workbook

Wed May 02, 2007 3:37 pm
If L and W represent the length and width of a rectangle, respectively, what is the peremeter?

(1) 2l + w = 40

(2) l+w = 25

I thought the answer was A, but I was wrong...

According to the solution set, the answer is b cuz you can solve the problem by the following equation.

How would you get the perimeter if you have the info in B?

Perimeter = 2(l+w). Knowing the value of l+w can easily give
the perimeter. Hence B
