a. Use the common method to calculate
b. On graph paper, draw an array for
c. Write equations that use the distributive property and that correspond to the steps in the common method in part (a).
d. Use the common method to calculate
e. On graph paper, draw an array for 37 x 24 (or draw a rectangle to represent such an array). Subdivide the array in a natural way so that the parts of the array correspond to the steps of the common method in part (d). Compare with part (b).
f. Write equations that use the distributive property and that correspond to the steps in the common method in part (d). Are these the same equations as in part (c)?
g. Other than the distributive property, which you used in parts (c) and (f), which property of arithmetic is relevant to this problem? Explain and discuss.

In Exercises 45-46, you will use mathematics, not your eyes, to observe the irregularities. B A 45. Find the sum of the angle measures at vertex A. Then explain why the tessellation is a fake. 46. Find the sum of the angle measures at vertex B. Then explain why the tessellation is a fake. =et at If se Fic SECTION 10.3 Polygons, Perimeter, and Tessellations 645 61. I find it helpful to think of a polygon's perimeter as the length of its boundary. 62. If a polygon is not regular, I can determine the sum of the measures of its angles, but not the measure of any one of its angles. 63. I used floor tiles in the shape of regular pentagons to completely cover my kitchen floor.
