Underlying Processes and Mathematical Tools
Performance Task
A brick company manufactures decorative bricks in the shape of isosceles trapezoids. The longer base of the smallest trapezoid is 20cm. The legs of this trapezoid are 4cm long each, and the trapezoid has a perimeter of 43cm.
The next larger trapezoid has the same base lengths as the first, and has a perimeter of 51cm.
The third trapezoid in the series has the same base lengths as the other two, and a perimeter of 67cm.
If this pattern continues, find the area of the tenth brick. Justify your answer.
[pic]
This task is an example of assessing multiple concepts and processes within one problem. In this problem, students use, at the least, the concepts of area of a trapezoid, applications of the Pythagorean Theorem, functional relationships, and properties and attributes of functions. Geometric relationships, including the area of a polygon, and patterns and algebraic relationships are concepts addressed in different strands of the 8th grade and Algebra I TEKS as well as Objectives 1, 2, 6, 8, and 10 of the Grade 9 Texas Assessment of Knowledge and Skills (TAKS).
