Draw a generic rectangle to help you calculate each product. For each part, write: (total dimension)(total dimension) = sum of individual area parts = total area. For example, the diagram at right shows that
Think back to the way you solved the generic rectangles in class. Change 73 to 70 + 3. Change 42 to 40 + 2.
Part of the rectangle has been filled in for you.
Generic rectangle
top edge left
top edge right blank
left edge top blank
inteterior top left
interior top right blank
left edge bottom
interior bottom left blank
interior bottom right
This one is solved just like the one at left. Remember to add a hundreds place column.
Generic rectangle | top edge left | top edge right |
left edge top | interior top left | interior top right |
left edge bottom | interior bottom left | interior bottom right |
