Make the smallest number 1 and the largest number as small as possible. Again, the largest number should be as small as possible. Floobini's lazy rival, Gloobini, has stolen Floobini's trick. Although the trick works, the largest number in the set has increased. Count any square that has a checker at each corner.
Squares can be any size, straight or tilted.
Remember that the squares can be any size, straight or tilted. The figure below shows an L-shaped area outlined with matchsticks. The area of the shape is three squares, and there are eight matchsticks. Using the matchsticks as the edges of a grid, find a shape that uses the same number of matchsticks as its area. Just as a square's area can equal its perimeter, a circle's area can equal its circumference.
