Intro
Generic Rectangles can be used to visualize multiplication of larger numbers by breaking the large numbers into smaller parts. They use area to visualize the multiplication. It also provides a way to arrange work to prevent mistakes. They are called generic rectangles because they are usually not drawn to scale. Try some Practice Problems with answers down below.
Practice Questions
Fill out each generic rectangle and state the final product.
\(\textbf{1)}\) \(203 \times 47\)
\(203 \times 47 = 9{,}541\)
\(\textbf{2)}\) \(320 \times 72\)
\(320 \times 72 = 23{,}040\)
\(\textbf{3)}\) \(540 \times 37\)
\(540 \times 37 = 19{,}980\)
\(\textbf{4)}\) \(1{,}200 \times 340\)
\(1{,}200 \times 340 = 408{,}000\)
\(\textbf{5)}\) \(420 \times 210\)
\(420 \times 210 = 88{,}200\)
\(\textbf{6)}\) \(310 \times 85\)
\(310 \times 85 = 26{,}350\)
