\nExercise 1.<\/p>\n
Draw a picture that shows why 5 copies of the rectangle with sides 1\u00a0and b make the rectangle with sides 5 and b.<\/p>\n
Let n be a whole number. Note that n copies of the rectangle with sides 1 and b\u00a0make the rectangle with sides n and b. It follows the rectangle with sides n and\u00a0b has n times as much area as the rectangle with sides 1 and b. Hence, we must\u00a0assign nb to the measure of the area of the rectangle with sides n and b (why?).<\/p>\n

Example 2.<\/p>\n
Let’s use the area model definition of multiplication to show that 3(4) = 12. First we construct a rectangle with sides 3 and 4 as shown below.
\nNext partition the rectangle into unit squares.
\nAnd finally place the top two rows alongside the bottom one.<\/p>\n
