2-75.

Solve each generic-rectangle puzzle. For each part, write a multiplication sentence, as you did in problem 2-72.

1.  Generic Rectangle Top Edge Left is blank Top Edge Right is $+4$ Left Edge Top is $30$ Interior Top Left is $1500$ Interior Top Right is blank Left Edge Bottom is blank Interior Bottom Left is $250$ Interior Bottom Right is blank.
• What do you need to multiply $30$ by to get $1500$? This will give you the top edge length of the rectangle. Can you then figure out what must go below the 30 in order to get the area of 250?

1.  Generic Rectangle Top Edge Left is blank Top Edge Middle is Blank Top Edge Right is$+7$ Left Edge Top is $40$ Interior Top Left is blank Interior Top Middle is $2400$ Interior Top Right is blank Left Edge Bottom is blank Interior Bottom Left is $1600$ Interior Bottom Middle  is blank Interior Bottom Right is $56$
• Some missing parts have been filled in. Do they make sense? Now try to fill in more parts yourself.

 Generic Rectangle Top Edge Left is blank Top Edge Middle is  $\color{blue}{60}$ Top Edge Right is$+7$ Left Edge Top is $40$ Interior Top Left is  $\color{blue}{8000}$ Interior Top Middle is $2400$ Interior Top Right is $\color{blue}{280}$ Left Edge Bottom is blank Interior Bottom Left is $1600$ Interior Bottom Middle  is blank Interior Bottom Right is $56$
