A rectangular yard measures 40 feet by 25 feet. How much fencing is needed to enclose it completely?

Correct answer to question 50 (Arithmetic Reasoning): 130 feet

Method

Fencing runs around the outside, which is the perimeter rather than the area. Adding one long side and one short side gives 65 feet, and doubling that for both pairs gives 130 feet. The 1,000 figure is the area, a common trap.
