Perimeter+and+Area

RMT Possible Points = 4 (MC, GR)
 * Find the perimeter of polygons and the area of triangle and trapezoids.**


 * Drawings may be used.
 * Any representation of a rational number may be used.
 * Word problems/real-life situations may be used.
 * Determining the perimeter of a regular polygon may be required.
 * Unnecessary dimensions may be included.
 * The properties of all types of triangles may be required to determine the area of a triangle.

Sample problems from Item Specs

[|Find the Perimeter and Area of Quadrilaterals] Students will learn about the different types of quadrilaterals and be able to distinguish between each. They will also work with forumulas to find the perimeter and area of each shape.
 * Interwrite Lesson**

[|Dividing up the area] In this TI-73 activity, students will use the Geoboard application to compare the areas of squares, rectangles, and parallelograms to the area of the triangles that divide each of them. They are to determine a formula for the area of a triangle. Then students will compare parallelograms and rectangles that have the same area to determine the relationship between the two quadrilaterals. As an extension, students will use what they have learned in the activity to find the area of complex figures.
