8-58.

Solve each generic rectangle puzzle. Write your answer in the form:
(total length)(total width) = sum of individual area parts = total area.

1.  Generic Rectangle Top edge left, blank Top edge right$+6$ Left edge top$20$ Interior top left$1600$ Interior top right, blank Left edge bottom, blank Interior bottom left$560$ Interior bottom right, blank

Multiply $6$ and $20$ to get the cell to the right of $1600$. Next, find the cell to the left of $+6$ by dividing $1600$ by $20$. Do a similar process to find the other two cells.

1.  Generic Rectangle Top edge left, blank Top edge middle, blank Top edge right$+5$ Left edge top$30$ Interior top left, blank Interior top middle$2700$ Interior top right, blank Left edge bottom, blank Interior bottom left$3600$ Interior bottom middle, blank Interior bottom right, $45$

First, multiply $30$ by $+5$ to get the cell above $45$. Next divide $2700$ by $30$ to get the cell above $2700$. Third, divide $45$ by $5$ to get the cell below $30$. Continue a similar pattern to find the other numbers in the table.
