In the “Toothpick and Tiles” game, you looked at the number of square tiles and the number of toothpicks used to form shapes. The math words that describe the number of tiles and toothpicks are *area* and *perimeter*. Read the Math Notes box for this lesson to review how area and perimeter are related to tiles and toothpicks. Then follow the directions below.

Find the area and perimeter of the tile figure at right.

Count the squares in the rectangle to find the area. How does the number of squares relate to the base and height?

Try adding up all the sides of the rectangle to find the perimeter:
