Copy and complete these generic rectangles on your paper. Then write the area of each rectangle as a product of the length and width and as a sum of the parts.
Generic rectangle
left edgeinterior left blank
interior right blank
bottom edge left
bottom edge right
To write the area as a sum:
Find the area of each of the rectangle's sections. Then, add them together.To write the area as a product:
Multiply the total length by the total width, but don't simplify it.As a sum:
As a product:
Generic rectangle left edge top
interior top left blank
interior top right blank
left edge bottom
interior bottom left blank
interior bottom right blank
bottom edge left
bottom edge right
See the help for part (a).
As a sum:
As a product:
Generic rectangle interior left
interior middle
interior right
Find the greatest common factor of the areas. That will be the width. Then divide each area by the width to find the length. Then follow the steps for part (a).
