If a rectangular billboard has an area of 117 square feet and a perimeter of 44 feet, what is the length of each of the shorter sides? Choose the correct choice from the following:
A) 4 B) 7 C) 8 D) 9 E) 26
This question can be solved algebraically or by TESTing THE ANSWERS.   We're told that a rectangle has an area of 117 and a perimeter of 44. We're asked for the length of one of the SHORTER sides of the rectangle.   Since the answers are all INTEGERS, and the area is 117, the shorter side will almost certainly be less than 10 (since 10x10 = 100, but we're NOT dealing with a square). Answer B (7) does NOT divide evenly into 117, so the correct answer is   Let's TEST Answer D: 9   IF...   The shorter side = 9...   The area = 117....117/9 = 13 = the longer side   Perimeter = 9+9+13+13=
