Let’s get out our math journals and  work through the following application problem. Make sure you read the problem carefully, draw a picture to match your thinking and write and solve an equation.

Read, Draw, Write, DONE!

R (Read the problem carefully.) Maris has 2 small, square flower beds on either side of her front door, and she wants to buy plastic border to go all the way around both beds.  She measured the side closest to her stairs, and it measured 50 inches.  How much total border should she buy, to cover the perimeter around both square flower beds? D (Draw a picture.) W (Write and solve an equation.)
