Stewart draws a triangle, and each side is 2 1/6 inches long. Judith draws a square, and each side is 1 5/8 inches long. What figure has the greatest perimeter, the triangle or the square?
Perimeter of triangle drawn by Stewart will be = 3 x length of each side (triangle has 3 sides, all are equal in this problem)
i.e. 3 x 2 1/6 = 3 x 13/6 = 13/2 inches
Perimeter of square drawn by Judith will be = 4 x length of each side (square has 4 equal sides)
i.e. 4 x 1 5/8 = 4 x 13/8 = 13/2 inches
From above calculations we found that both the figures have equal perimeters.
