CPM Homework Help : MC1 Problem 5-22

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

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

Hint (a):

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.

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, $45$

Hint (b):

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.
