Mr. Wynn now wants to cover a part of the gym with butcher block paper to work on a large painting. He covers a section of the gym that is 30 feet long and 35 feet wide. Then he realizes he needs a bit more space for the painting and adds a section of butcher block that is 4 feet long and 35 feet wide.
a. How many square feet of butcher block paper did Mr. Wynn use for his painting?
b. What is the total length and width of Mr. Wynn’s painting?

Modified by The Match Foundation, Inc.Label the area model to represent 31 x 23 and to find that product.
a. Decompose each number into its base-ten units (tens and ones) and write them in the boxes on each side of the rectangle.
b. Label regions A, B, C, and D with their areas. Show your reasoning.
c. Find the product that the area model represents. Show your reasoning.
Here is one way to calculate 31 x 23. Each number with a box gives the area of one region in the area model.
a. In the boxes next to each number, write the letter of the corresponding region.
b. There is a 1 above the hundreds digit in the sum. What does that 1 represent?
