Remarks/Examples
Students should recognize that the area of a piece of paper might be measured in square inches, the area of a room might be measured in square feet, and the area of a large piece of land might be measured in square miles. Alternately, these measurements might be in square centimeters, square meters, and square kilometers, respectively.Example: Students find the area of a composite shape. An Lshaped region may be decomposed into rectangular regions.
Example: Find the area of the polygon in the picture. Explain or show how you found the area.

 Clarification :
Students will find the area of a rectangle by multiplying the base by the height.
Students will solve problems involving the area of a rectangle or a composite shape composed of adjacent rectangles, such as L or Eshaped figures.
Students will select appropriate units and/or tools to estimate and/or solve realworld area problems, (e.g., recognize that the area of a room is expressed as square feet, compared to an area of land expressed in square miles or kilometers).  Content Limits :
Items may include figures with wholenumber dimensions of 100 or fewer units.
Items will not include the formula for area of a rectangle.  Stimulus Attributes :
Items may be on a grid, but this is not required.
Graphics should be used in most items.
Students may be required to use a ruler to measure the dimensions of a figure to determine its area.  Response Attributes :
Responses may include incorrect units of measurement.
